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 with a background worker that scans artists, albums, and tracks in priority order. Stores style, mood, and AudioDB IDs with automatic backfill of artwork and genres.
Includes artist ID cross-verification from album/track results to correct mismatches caused by same-name artists.
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.
