Implements lazy loading of artist images in search results, artist pages, and similar artist bubbles to improve performance and user experience. Updates the iTunes client to prefer explicit album versions and deduplicate albums accordingly. Adds a new API endpoint to fetch artist images, and updates frontend logic to asynchronously fetch and display images where missing. |

File Organization
Default Structure
Transfer/Artist/Artist - Album/01 - Track.flac
Custom Templates
- Albums:
$albumartist/$albumartist - $album/$track - $title - Singles:
$artist/$artist - $title/$title - Playlists:
$playlist/$artist - $title - Variables:
$artist,$albumartist,$album,$title,$track,$playlist
Features: Client-side validation, automatic fallback, instant apply
Troubleshooting
Enable Debug Logging: Settings → Log Level → DEBUG → Check logs/app.log
Common Issues
- Files not organizing: Verify transfer path, check template syntax, use "Reset to Defaults"
- Docker paths: Ensure drives mounted in docker-compose.yml, use
/host/mnt/X/prefix - OAuth from remote: Manually edit callback URL to server IP (Spotify requires 127.0.0.1)
- Wishlist stuck: Auto-retry runs every 30 mins, check logs for failures
- Multi-library: Select correct library in settings dropdown
Roadmap
Planned
- WebSocket support (replace polling)
- Batch wishlist operations
- Download history browser UI
- Source reliability tracking
- Notification center
- Mobile-responsive improvements
Under Consideration
- MusicBrainz ID integration
- Additional streaming sources (Deezer, Apple Music)
- Playlist collaboration between instances
- Machine learning for matching
