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
When downloading an album/EP, perform a single album-level search on Soulseek to find a user with the complete album folder before falling back to per-track search. This improves album completion rates and ensures consistent quality across tracks.
Add a /callback Flask route (port 8008) that handles Spotify OAuth token exchange, mirroring the existing HTTPServer handler on port 8888. This allows users behind a reverse proxy to point their Spotify redirect_uri at the main app.
Root cause: When album downloads completed, the frontend immediately closed
the modal and called /api/playlists/cleanup_batch, which deleted the batch
from memory. The wishlist processing thread (submitted to executor) would
then try to access the batch and fail silently because it was already deleted.
This explains why:
- Wishlist auto-processing worked (different timing/3-second delay)
- Manual "Add to Wishlist" button worked (different code path, before downloads)
- Album modal failed tracks didn't get added (race condition)
The fix prevents batch cleanup until wishlist processing completes:
Backend (web_server.py):
1. Mark wishlist_processing_started=True when submitting processing job
2. Mark wishlist_processing_complete=True when processing finishes
3. Block cleanup endpoint if processing in progress (return 202)
Frontend (script.js):
4. Handle 202 response and retry cleanup after 2-second delay
This eliminates the race condition while maintaining async processing and
ensuring all failed/cancelled tracks are properly added to the wishlist.
Issue: Tracks marked as failed or cancelled in the download missing tracks modal
were not being automatically added to the wishlist on completion, despite manual
"Add to Wishlist" button working correctly. Modal completed silently without
mentioning wishlist.
Root cause: Line 549 in web_server.py was calling _on_download_completed() with
wrong parameters - missing batch_id. This caused the completion handler to look
up wrong batch, return early, and never process failed tracks to wishlist.
The bug affected downloads that complete via monitor detection (YouTube, Soulseek)
since the monitor loop calls this function when it detects completed transfers.
Fix: Added missing batch_id parameter to _on_download_completed() call on line 549.
Changed:
_on_download_completed(task_id, success=True)
To:
_on_download_completed(batch_id, task_id, success=True)
Tested: Automatic wishlist addition now works correctly for failed/cancelled tracks.
Frontend: treat discover_album_ playlists as Album Downloads to ensure proper folder structure for Recent Releases.
Backend: inject explicit album context into Wishlist download tasks to force Artist/Album/ grouping instead of flat file handling.
Library page was using album data from discography listing while Artists page used track.album from API. With iTunes, these could have different track counts, causing different album_type classifications.
- Updated handleAddToWishlist to use track.album data like Artists page does
- Added album_type copying to owned releases in merge_discography_data
