When clearing the wishlist or changing the discovery lookback period, reset watchlist_artists.last_scan_timestamp to NULL so subsequent scans can re-discover older releases that were previously filtered by an earlier scan timestamp. clear_wishlist now deletes wishlist_tracks, updates last_scan_timestamp for all watchlist artists, and logs the number of tracks cleared and artists reset. set_discovery_lookback_period also resets last_scan_timestamp and reports how many artists were reset. Minor whitespace cleanups in watchlist_scanner and web_server included.
Add a release_date field to the Track dataclass for both iTunes and Spotify clients (iTunes: parsed from releaseDate, Spotify: from album.release_date). Propagate release_date into enhanced search results in web_server and into the client-side script so album objects include release_date when available. Also broaden playlistId matching in the missing-tracks process to include 'enhanced_search_track_'. Removed SQLite SHM/WAL files from the repo (cleanup of DB temporary files). These changes enable showing and using track release dates across the app.
Add per-track selection checkboxes, select-all control and a selection count to download modals (missing/YouTube/Tidal/artist-album). Implement JS helpers (toggleAllTrackSelections, updateTrackSelectionCount) to manage checkbox state, row dimming, button disabling, and to filter/stamp selected tracks with _original_index before sending to the backend. Update start/add-to-wishlist flows to use only selectedTracks and disable controls once analysis starts. Backend _run_full_missing_tracks_process now reads _original_index to preserve original table indices in analysis results. CSS updates (mobile.css and style.css) add styling for checkbox columns, responsive hiding logic for headers/columns, selection visuals (.track-deselected), and small layout/width tweaks.
Introduce M3U export feature with UI control and server-side saving. Adds a new m3u_export config option (enabled flag) and a checkbox in the settings UI. The web endpoint /api/save-playlist-m3u now checks the m3u_export setting (unless force=true), builds the target folder using a new _compute_m3u_folder() helper (leveraging existing template logic with sensible fallbacks), sanitizes filenames, and writes .m3u files into the computed folder. Frontend JS loads/saves the new setting, supplies album/artist metadata when auto-saving, and both autoSave and manual export now POST M3U data to the server (manual export uses force=true). Also changed browser download filename extension to .m3u and added minor logging/response behavior.
Introduce deferred album repair scanning and robust tracklist resolution plus UI/presentation tweaks.
- core/repair_worker.py: Add lazy MusicBrainz and AudioDB client accessors, per-batch folder queues, and register_folder/process_batch to defer folder scans until a batch completes. Implement cascading tracklist resolution (_resolve_album_tracklist) using Spotify/iTunes IDs, Spotify track→album lookup, album search, MusicBrainz release lookup, and AudioDB→MusicBrainz fallback. Add helpers to read Spotify track IDs, MusicBrainz album IDs, album/artist tags from files, MB/AudioDB fetchers, placeholder-ID filtering, and rename associated .lrc files when renaming audio files. Cache/locking and background-threaded scanning included. Improves resilience to missing/placeholder IDs and avoids circular imports.
- web_server.py: Register album folders for repair in post-processing and trigger repair_worker.process_batch when batches complete (multiple completion paths) so scans run after downloads finish.
- webui/static/script.js: Reduce unnecessary background work by skipping many fetches when the tab is hidden, and refresh dashboard-specific data on visibility change to ensure UI updates after OAuth or tab switch.
- webui/static/style.css: Replace glassmorphic backdrop-filters with opaque dark gradients for sidebar and main content to improve GPU rendering and visual consistency.
Overall: Adds reliable post-download album repair scanning using multiple metadata sources and reduces unnecessary client polling and heavy CSS effects for better performance and robustness.
Introduce an optional "Blasphemy Mode" that deletes the original FLAC after a verified MP3 copy is created.
- config: add lossy_copy.delete_original (default: false).
- webui/index.html & static script: add checkbox and warning in settings UI and persist the setting.
- web_server.py: make _create_lossy_copy return the MP3 path when it deletes the FLAC (otherwise None); validate the MP3 using mutagen before removing the FLAC; rename associated .lrc files if present; update post-processing to use the final processed path in logs and wishlist checks and to consider .mp3 variants when FLAC may have been removed.
Behavior is off by default and includes safety checks and logging to avoid accidental deletion of originals.
Add full-featured SpotifyWorker and iTunesWorker background workers to enrich artists, albums, and tracks with external metadata using batch cascading searches, fuzzy name matching, ID validation, and DB backfills. Update RepairWorker to re-read the transfer path from the database each scan, resolve host paths when running in Docker, and trigger immediate rescans when the transfer path changes; remove the static config_manager dependency. Also include supporting changes to the database layer and web UI/server (stats, controls, and styles) to integrate the new workers and reflect updated worker status.
Add _get_playlist_items_page to call the new playlists/{id}/items endpoint (Feb 2026 API migration) and fall back to spotipy.playlist_items (old /tracks) on 403/404. Update _get_playlist_tracks and web_server.get_playlist_tracks to use the new helper to avoid 403 errors for Development Mode apps while preserving compatibility with Extended Quota Mode.
Tighten fuzzy matching in post-processing when no exact context is found: acquire matched_context_lock for thread-safe access and limit candidate keys to those starting with the current username prefix ("{task_username}::") while still matching the file basename. This prevents cross-album/username metadata contamination during mass downloads (e.g., multiple albums with identical track basenames) and reduces erroneous fuzzy matches.
Use MusicBrainz IDs returned by AudioDB as fallbacks when MB lookup is missing. The patch maps strMusicBrainzID/strMusicBrainzAlbumID/strMusicBrainzArtistID to MUSICBRAINZ_RECORDING_ID, MUSICBRAINZ_RELEASE_ID, and MUSICBRAINZ_ARTIST_ID respectively (only if those tags are not already present), sets recording_mbid and artist_mbid where applicable, and adds informational prints for debugging.
Request recording 'releases' from MusicBrainz and, when available, capture the first release MBID into id_tags['MUSICBRAINZ_RELEASE_ID']. Persist this release (album) MBID across tag formats by adding TXXX ('MusicBrainz Album Id'), a generic tag 'MUSICBRAINZ_ALBUMID', and an iTunes MP4 freeform key. This allows tracks to be associated with their MusicBrainz release/album.
Stop recomputing expected file paths during verification and instead use the exact path computed/moved during post-processing (context['_final_processed_path']). If that context value is missing, assume success to avoid false failures and mark the task completed.
Also store the computed final path into context in _post_process_matched_download so verification uses the exact same path. Add logic to handle cases where the source vanished but a variant (quality-tagged) file exists in the destination — treat that as success, set the final path, download art and generate LRC.
In the post-processing worker: skip verification when the task is already completed or marked as stream_processed, check for stream_processed status while searching, increase file search retries from 3 to 5 with longer sleeps, and re-check stream_processed before marking a task failed. Improve log messages and error text to reduce false negatives caused by independent recomputation or concurrent stream processing.
Add a recovery step during wishlist processing that scans in-memory download_tasks (under tasks_lock) for tasks marked 'failed' or 'not_found' but not present in permanently_failed_tracks, and appends normalized track entries (including retry_count, failure_reason, spotify_track, and cached candidates). This prevents tasks that were force-marked failed by stuck-detection logic from being silently skipped in wishlist sync. Also fix post-processing context lookup by rebuilding the context key with _make_context_key(task_username, task_filename) so it matches how context keys are stored.
Introduce a RepairWorker to scan the transfer folder and automatically detect/repair broken album track numbers (e.g. the "all tracks = 01" bug). The worker uses mutagen to read/write tags, fuzzy-matches titles against an album tracklist (Spotify/iTunes via a SpotifyClient), updates filenames and the tracks DB file_path when renamed, and caches album tracklists. It also adds DB schema support (repair_status, repair_last_checked, and an index).
Integrates the worker into the web server: initializes and starts the worker, and exposes /api/repair/status, /api/repair/pause and /api/repair/resume endpoints. Adds UI elements (button, tooltip), client-side JS to poll and control the worker, CSS for visuals/animations, and a new image asset (whisoul.png).
Introduce a Hydrabase P2P mirror worker and integrate it into the web UI and server flows. Adds core/hydrabase_worker.py: a background thread with a capped queue (1000), enqueue API, rate limiting, basic stats (sent/dropped/errors), and logic to send JSON requests over a provided WebSocket (responses received and discarded). Integrates the worker into web_server.py (import, startup init, status/pause/resume endpoints, and enqueues queries from multiple search endpoints when dev mode is enabled). Adds UI elements, JavaScript polling/toggle logic, and CSS styling for a Hydrabase status button in webui (index.html, static/script.js, static/style.css) to display and control worker state.
Introduce a developer-only Hydrabase testing UI and backend WebSocket integration. Adds a simple dev-mode toggle (password 'hydratest') and new API endpoints (/api/dev-mode, /api/hydrabase/connect, /api/hydrabase/disconnect, /api/hydrabase/status, /api/hydrabase/send) that use websocket-client to connect/send raw JSON to a Hydrabase instance. Frontend changes include a Hydrabase nav/page, payload editors, response panel, dev-mode UI in Settings, associated JS handlers, CSS styling, and an icon asset. Also add websocket-client to requirements.
Introduce $artistletter and $disc template variables across config, UI, and backend to support artist-first-letter tokens and multi-disc albums. Update web_server.py to include disc_number in template context, prefer user-controlled $disc in templates, and create configurable disc subfolders using a new file_organization.disc_label setting. Update example and active config, web UI to expose the new variable and disc label selector, and script.js to validate, load, and save the new settings and substitutions.
Introduce a configurable "lossy_copy" feature that creates an MP3 copy alongside downloaded FLAC files. Adds default config (example and runtime) and UI controls for enabling the feature and selecting an MP3 bitrate. Implements _create_lossy_copy in web_server.py which checks the FLAC extension, respects the configured bitrate (default 320 kbps), locates ffmpeg (including a local tools/ffmpeg fallback), performs conversion, and attempts to update the QUALITY tag via mutagen. The feature is invoked after post-processing/moving downloads. Logs and graceful failures (missing ffmpeg, timeouts, tag errors) are included.
Introduce a new $quality template variable that is only substituted into filenames to avoid splitting album folders when tracks of mixed qualities are present. Updates include:
- web_server.py: populate template contexts with 'quality' (from context['_audio_quality']), strip $quality from folder components, substitute it only in the filename, and clean up empty brackets/parentheses/dashes when the variable is empty.
- config/config.example.json and config/config.json: document the new variable in the file_organization template variables string.
- webui/index.html and webui/static/script.js: update UI help text and client-side template validation to include $quality.
This prevents folder fragmentation for albums with mixed-quality files while still allowing quality information in filenames.
Add Deezer as a third metadata enrichment source. Enriches tracks with BPM and explicit flags, albums with
record labels, explicit flags, and type classification (album/single/EP), and backfills artwork and genres across
all entities. Includes background worker with priority queue, rate-limited API client, database migration, server
endpoints, and UI button with purple-themed status tooltip.
Integrated TheAudioDB as a metadata enrichment source. A background worker scans the library in priority order (artists → albums → tracks), matching entities via fuzzy name comparison and storing style, mood, and AudioDB IDs. Includes rate limiting, 30-day retry for not-found items, and a UI tooltip showing phase-based scan progress.
Add a UI button to disconnect Spotify and fall back to iTunes/Apple Music without restarting. Cache is_spotify_authenticated() with a 60s TTL to reduce redundant API calls (~46 call sites were each
triggering a live sp.current_user() call). Fix status endpoint calling the auth check twice per poll,
and ensure both OAuth callback handlers (port 8008 Flask route and port 8888 dedicated server)
invalidate the status cache so the UI updates immediately after authentication.
Spotify's @rate_limited decorator now retries on 429/5xx with exponential backoff (up to 5 retries) instead of sleeping once and raising. Watchlist scan delays scale dynamically based on lookback setting and artist count to prevent sustained API pressure. A circuit breaker pauses the scan after consecutive rate-limit failures.
When a download fails in the Download Missing Tracks modal, hovering over the "Failed" status now shows a tooltip explaining why. The backend already tracked error_message on tasks internally but never sent it to the frontend. This surfaces those reasons and enriches them with detailed context — search diagnostics break down what happened per query (no results, filtered out, search error), retry failures include source counts and likely cause, and timeout/stuck messages name the state and duration. The tooltip uses a fixed-position popup to avoid clipping by the modal's scroll container, with scroll and visibility-aware dismissal.
The Soulseek "Test Connection" button could report success while the dashboard status remained "Disconnected" because the status endpoint only checked if slskd was configured (is_configured()), not actually
reachable (check_connection()). Switched to a real connection check with TTL caching (matching the existing
Spotify/media server pattern), update the status cache after successful tests, and refresh the UI immediately on success.
Multi-disc albums (e.g., deluxe editions, double albums) now automatically organize
tracks into Disc 1/, Disc 2/ subfolders within the album folder. Detection uses the
disc_number field from Spotify's API — when an album has total_discs > 1, subfolders
are created. Single-disc albums are completely unaffected.
- Plumb disc_number through all download paths (enhanced, non-enhanced, download
missing modal, wishlist)
- Compute total_discs from album tracklist and store on album context
- Modify path builder to insert Disc N/ subfolder for multi-disc albums
- Preserve disc_number when tracks fail and get re-added to wishlist
- Preserve disc_number when adding tracks to wishlist from library page
- Add visual disc separators in Soulseek search result track lists
Split the enhanced search dropdown into distinct Albums and Singles & EPs sections using the album_type field. Changed the zero-tracks error from a cryptic red error toast to a clear warning message. Fixed the loading text to show the actual music source name instead of hardcoded "Spotify".
Automatically clear completed downloads from slskd after batch completion, matching the cleanup behavior already present in the frontend. Adds a 5-minute periodic sweep as a safety net when no batches are actively running.
When clicking a partially-complete album on the Library page, the wishlist modal now shows which tracks are owned (dimmed with checkmark) and which are missing (orange border). Ownership data lazy-loads after the modal opens to avoid blocking the UI, using a batch DB query for speed. Also fixes albums like DAMN. showing "14/15" when all available tracks are owned — the frontend now trusts the backend's "completed" status instead of doing raw track count math against potentially inaccurate Spotify metadata.
Replace blocking DB matching in the Library artist detail view with a two-phase render pattern. The page now renders album cards instantly from Spotify/Itunes data , then streams per-release ownership results via SSE that update cards one-by-one.
Update version to 1.6 in sidebar and API. Add changelog for local import, enhanced tagging, mobile layout, and performance improvements. Fix track popularity field access for upcoming Spotify API changes (February 2026).
Added an Import feature that lets users process local audio files through the existing post-processing pipeline (metadata enrichment, cover art, lyrics, library organization). Files are placed in a configurable Staging folder and imported via two modes: Album mode (search/match files to a Spotify tracklist) and Singles mode (select individual files for processing). Includes auto-suggested albums based on staging folder contents and real-time per-track progress tracking.
- Add global discovery_match_cache table to cache successful track matches
(title+artist+provider -> matched result) across all discovery sources
- Cache check before API search in YouTube, ListenBrainz, Tidal, and Beatport
discovery workers; cache write after high-confidence matches
- Re-discovering playlists or overlapping tracks across sources skips API lookups
- Fix Spotify tab sidebar forcing 2-column grid on mobile via inline JS styles
- Add mobile responsive styles for Spotify playlist cards (stack layout vertically)
Enrich downloaded audio files with external identifiers and improved genre metadata in a single post-processing write. During metadata enhancement, the app now looks up the MusicBrainz recording and artist MBIDs, retrieves the ISRC and MusicBrainz genres from a follow-up detail lookup, merges them with Spotify's artist-level genres (deduplicated, capped at 5), and embeds everything alongside the Spotify/iTunes track, artist, and album IDs. All MusicBrainz API calls are serialized through the existing global rate limiter, making concurrent download workers safe without needing to pause the background worker. Includes a database migration adding Spotify/iTunes ID columns to the library tables.
Add optional post-download audio fingerprint verification using AcoustID.
Downloads are verified against expected track/artist using fuzzy string
matching on AcoustID results. Mismatched files are quarantined and
automatically added to the wishlist for retry.
- AcoustID verification with title/artist fuzzy matching (not MBID comparison)
- Quarantine system with JSON metadata sidecars for failed verifications
- fpcalc binary auto-download for Windows, macOS (universal), and Linux
- MusicBrainz enrichment worker with live status UI and track badges
- Settings page AcoustID section with real-fingerprint connection test
- Source reuse for album downloads to keep tracks from same Soulseek user
- Enhanced search queries for better track matching
- Bug fixes: wishlist tracking, album splitting, regex & handling, log rotation
MusicBrainz library enrichment with real-time
status monitoring and manual control.
Features:
- Status icon button in dashboard header with glassmorphic design
- Animated loading spinner during active enrichment
- Hover tooltip showing:
- Worker status (Running/Paused/Idle)
- Currently processing item
- Artist matching progress with percentage
- Click-to-toggle pause/resume functionality
- Auto-polling every 2 seconds for live updates
Backend Changes:
- Added GET /api/musicbrainz/status endpoint
- Added POST /api/musicbrainz/pause endpoint
- Added POST /api/musicbrainz/resume endpoint
- Worker tracks current_item for UI display
- get_stats() returns enhanced status data
Frontend Changes:
- New MusicBrainz button component with tooltip
- Premium CSS styling with animations
- JavaScript polling and state management
- Positioned tooltip below button with centered arrow
Files Modified:
- web_server.py: API endpoints and worker initialization
- core/musicbrainz_worker.py: current_item tracking
- webui/index.html: Button and tooltip structure
- webui/static/style.css: Complete styling (240 lines)
- webui/static/script.js: Polling and interaction logic (115 lines)
- Files downloaded from different soulseek sources carried conflicting MusicBrainz Release IDs and disc number tags that were never overwritten during metadata enhancement, causing Navidrome/Plex to split a single album into multiple entries even when folder structure and album name were identical
- disc_number is now written to file metadata (sourced from Spotify/iTunes API), overwriting stale tags from soulseek sources
- MusicBrainz IDs are now stripped during metadata enhancement so media servers group by album name + artist instead of mismatched release IDs
- The verification worker now applies _resolve_album_group() for album name consistency with the stream processor path
- Fixed source reuse retry logic: used_sources is no longer reset between retries, so a source that errors during transfer is skipped on retry and the system falls through to a normal search instead of retrying the same failing source 3 times
Added per-context-key threading lock in _post_process_matched_download to serialize access when both the Stream Processor and Verification Worker attempt to process the same downloaded file. Previously, both threads would race to move the source file via shutil.move, causing FileNotFoundError for the loser. The lock ensures the first thread completes the move before the second enters, where existing protection checks detect the file was already transferred and return early.
- Single-worker mode for album batches (sequential downloads enable clean source reuse)
- Browse API integration to list files in a source's directory
- Failed source tracking per-batch to avoid retrying broken sources
- Graduated quality scoring for upload speed, queue length, and free slots
- Track number fallback fix (uses Spotify track number instead of hardcoded 1)
- Duplicate completion guard to prevent double-decrement of active worker count
- Dedicated logging for source reuse and post-processing diagnostics
