Register MusicBrainz as a first-class metadata source alongside Deezer, iTunes, Spotify, Discogs, and Hydrabase. Expose the shared client through metadata services, add the settings option, and expand the MusicBrainz search adapter with source-compatible artist, album, track, and detail methods.
Carry MusicBrainz IDs through similar-artist discovery, recommended artists, artist map serialization, and personalized playlist selection. Update DB migrations and lookup filters so similar_artist_musicbrainz_id is preserved on older schemas and used for source requirements and library exclusion.
Normalize MusicBrainz album adapter output for import context and add regression coverage for registry mapping, typed album conversion, and similar-artist filtering. Verified by user with 120 focused tests passing.
- Artist cards, hero section, and enhanced view now show Amazon Music badges
when amazon_id is populated (AMAZON_LOGO_URL constant, orange #FF9900 brand)
- Enhanced view artist and album match status rows include amazon_match_status
chip with click-to-rematch via openManualMatchModal
- getServiceUrl: added amazon (album/track ASIN → music.amazon.com) and fixed
missing discogs entries; serviceLabels adds tidal/qobuz/amazon
- Enhanced view enhanced-artist-id-badges includes amazon_id entry
- DB SELECTs for library artists list and artist detail now return amazon_id;
both response dicts include the field
- watchlist_artists migration adds amazon_artist_id column
- Watchlist config GET: amazon_artist_id in SELECT/WHERE/response (index 18)
- Watchlist artists list response includes amazon_artist_id
- link-provider endpoint: amazon added to valid_providers and col_map
- _populateLinkedProviderSection: amazonId param + Amazon Music source row
- Watchlist card source badges render Amazon pill (watchlist-source-amazon CSS)
- _openSourceSearch labels map includes amazon
- service_search: amazon_worker injected via init(); _search_service amazon branch
uses search_artists/albums/tracks, same {id,name,image,extra} return shape
- _SERVICE_ID_COLUMNS: amazon → amazon_id for artist/album/track
- _init_service_search call passes amazon_worker_obj
- amazon_client._fetch_album_metas: 5-minute TTL cache per ASIN — cached hits
skip _rate_limit() and HTTP call entirely; fixes ~10s artist detail load
- registry.py: removed amazon from METADATA_SOURCE_PRIORITY and
METADATA_SOURCE_LABELS — T2Tunes has no discography API, cannot serve as a
primary metadata source; Amazon remains a download source + ASIN enricher
- Settings metadata source dropdown and help text updated accordingly
Wires AmazonClient into the metadata source registry following the
exact same pattern as DeezerClient. No existing source paths touched.
- Add get_album_metadata / get_artist_info / get_artist_albums_list
aliases to AmazonClient (mirrors DeezerClient interface aliases)
- Register amazon in METADATA_SOURCE_PRIORITY and METADATA_SOURCE_LABELS
- Add _get_amazon_factory() + get_amazon_client() to registry.py
- Add amazon branch to get_client_for_source(); thread amazon_client_factory
kwarg through get_primary_client() and get_primary_source_status()
- Re-export get_amazon_client from the core.metadata_service shim
- Add Amazon Music option to Settings metadata source dropdown
- 3530 tests pass
- Keep the primary metadata provider snapshot generic and move Spotify auth/rate-limit details into a separate status object.
- Update the websocket fixture and dashboard/settings consumers to read the two buckets independently.
- Flatten the Spotify service-status rendering so it shows rate-limit and recovery states explicitly, while otherwise displaying the active metadata provider directly.
- Keep the Spotify auth controls and metadata-source picker aligned with the real session state after authenticate and disconnect flows.
- Return "Unmapped" for unknown metadata source labels instead of implying iTunes.
- Update the metadata registry tests to cover the new label fallback.
- Send Spotify auth completion back to the opener so the settings page refreshes immediately
- Make the local auth flow go straight through to Spotify instead of showing the temporary instruction page
- Keep the remote/docker instruction page available for manual callback setups
- Sync Spotify status, connect/disconnect buttons, and metadata source selection after auth and disconnect
- Keep the disconnect behavior aligned with the active primary metadata source
- Hide the auth button when a Spotify session is active
- Treat disconnect as a session change, not a provider swap
- Share metadata source labels in the registry
- Tighten rate-limit copy around Spotify-specific behavior
- let core.metadata.registry own per-profile Spotify client caching
- register the DB-backed profile credentials provider from web_server.py
- invalidate only the affected profile cache entry on save, delete, and auth
- make web_server.py read and refresh Spotify from core.metadata.registry
- add single-key metadata cache eviction for Spotify reauth
- export the new cache helper through the metadata package shims
