Phase 4 of service integration:
- Add provider adapters (MusicBrainz, Discogs to unified DTOs)
- Add RemoteMetadataState with search_albums and get_album_metadata
- Create remote_metadata commands module with Tauri handlers
- Wire up state and commands in lib.rs
Available commands:
- remote_metadata_search: Search albums on MusicBrainz or Discogs
- remote_metadata_get_album: Get full album metadata with tracks
- remote_metadata_cache_stats: Get cache statistics
- remote_metadata_clear_cache: Clear the in-memory cache
- Add PlaylistRule enum with BandMembers, ArtistGroups, CollaboratorNetwork variants
- Add GeneratedPlaylist struct for playlist preview results
- Add PlaylistGenerationConfig for customizing track limits
- Implement smart_playlist_preview command to generate playlists from MusicBrainz relationships
- Implement smart_playlist_resolve_artist helper to find artist MBID by name
- Implement smart_playlist_get_available_types to check what playlist types are available
- Search Qobuz for member/collaborator tracks and return matching track IDs
Add ListenBrainz scrobbling support with:
- Client module for ListenBrainz API
- Token-based authentication (user provides token from listenbrainz.org)
- Now-playing submission support
- Scrobble submission with MusicBrainz enrichment
- SQLite-based offline queue with TTL
- Credential persistence across sessions
- Settings UI for connection management
API integration uses Stage 1 MusicBrainz data to enrich scrobbles with
recording MBID, release MBID, and artist MBIDs when available.
cc
- Add MusicBrainz client with rate limiting (1 req/sec)
- Add SQLite cache with TTL for recordings, artists, releases
- Add Tauri commands for entity resolution
- Support ISRC, UPC/barcode, and name-based lookups
- Include artist relationship extraction (Stage 3 prep)
cc
- Add get_album_credits Tauri command with TrackCredits, AlbumCredits,
and AlbumInfo structs for consolidated album/track credits view
- Create AlbumCreditsModal component with two-column layout:
album info (artwork, metadata, quality badges) and collapsible
track list with performers and copyright
- Add Info button to AlbumDetailView header actions
- Integrate modal in +page.svelte with track play support
- Add PlaybackContext module with ContextManager
- Context tracks semantic origin (album, playlist, artist top, etc.)
- Separate from queue - defines what 'next' means
- Backend: Rust struct with track IDs and position tracking
- Frontend: Svelte store with reactive subscriptions
- Tauri commands for context CRUD operations
- Context is nullable (single track playback has no context)
cp
Backend changes:
- Add audio_diagnostics module to read actual hardware sample rate from /proc/asound
- New command get_hardware_audio_status() parses hw_params for real-time monitoring
- Add glob dependency for file pattern matching
Frontend (AudioOutputBadges):
- Implement 3-state DAC badge system:
- Green: DAC passthrough working correctly (rates match)
- Yellow: DAC passthrough ON but resampling detected (warning)
- Gray: DAC passthrough OFF (intentionally disabled)
- Dynamic tooltips showing actual hardware sample rate
- Compare file sample rate vs hardware sample rate
- Increase tooltip z-index to 9999 to prevent occlusion issues
- Add pointer-events: none to tooltip to prevent interaction issues
Frontend (SettingsView):
- Replace hardcoded "192 kHz" with dynamic hardware sample rate
- Load and display actual hardware audio status
- Show format details (e.g., S32_LE) when available
- Display "No active playback" when no audio is playing
- Add muted styling for inactive state
Frontend (QualityBadge):
- Add native tooltip showing tier and format
- Add cursor: help to indicate interactivity
i18n:
- Add "noActivePlayback" translations (EN/ES)
This allows users to verify bit-perfect playback is working and detect
resampling issues that would compromise audio quality.
Cherry-pick and integrate playlist import from playlist-import-impl branch:
- Add playlist_import Rust module with providers (Spotify, Apple, Tidal, Deezer)
- Add track matching algorithm (ISRC first, then fuzzy matching)
- Add PlaylistImportModal.svelte with progress log UI
- Wire up import button in Sidebar
- Add modal state management in uiStore
- Register Tauri commands for preview and execute
Original implementation by Codex, integrated manually due to branch divergence.
- Create share module with SongLinkClient for Odesli API
- Support for tracks via ISRC and albums via UPC
- In-memory cache with 1-hour TTL
- Commands: share_track_songlink, share_album_songlink
- Qobuz URL generators for tracks, albums, artists
- Proper error handling for missing identifiers
Settings:
- Add language dropdown (Auto, English, Español, etc.) with persistence
Last.fm:
- Create lastfm module with API client for authentication and scrobbling
- Add commands for auth flow, now playing, and scrobbling
- Full OAuth-style authentication with token exchange
- UI for entering API credentials and authorizing
- Automatic scrobbling after 50% of track or 4 minutes
- Update 'now playing' when tracks start
- Session persistence in localStorage
- Account section now shows real user name and subscription
- Logout button connected to logout handler
- Theme switching with persistence (Dark/Light/OLED Black/Warm)

- Cache stats display (size, max, track count)
- Clear cache functionality with disabled state
- Add notify-rust dependency for desktop notifications
- Create notification.rs commands module with show_track_notification and show_notification
- Register notification commands in lib.rs
- Wire up notifications in frontend for all playback scenarios:
- Search results playback
- Album track playback
- Playlist track playback
- Queue navigation and auto-advance
Backend:
- Add playlist.rs commands: get_user_playlists, get_playlist, search_playlists
- Add favorites.rs commands: get_favorites, add_favorite, remove_favorite
- Add API client methods: search_playlists, add_favorite, remove_favorite
Frontend:

- Add QueueManager in Rust backend with shuffle, repeat modes, and history
- Create queue Tauri commands (add, remove, next, previous, play_index, etc.)
- Wire Next/Previous buttons to backend queue
