|
|
|
|
## Features
|
|
|
|
### Home
|
|
- Hero card — large banner featuring a random pick from your most-played and recently played albums, labelled "Meistgespielt" or "Zuletzt gehört" accordingly
|
|
- Genre browser — top 15 genres (by song count) as a colored card grid; click to browse songs, hover-play to instantly shuffle the genre
|
|
|
|
### Music Library
|
|
- Stream music from your Navidrome / Subsonic library
|
|
- Browse artists, albums, playlists, starred tracks, and random picks
|
|
- Sort and filter views (albums, favorites) with chip filters
|
|
- Search/filter bar inside playlist detail and favorites (instant, client-side)
|
|
- Synced and plain lyrics via LRCLIB (auto-fetched per track)
|
|
- Play count display — optional toggle in Settings; always shown on artist pages
|
|
- Star and context-menu on every song row (artist top songs, all-songs view, playlists, albums)
|
|
|
|
### Playback
|
|
- Queue management with shuffle, repeat (all / once), and radio mode (endless random)
|
|
- Now Playing overlay with swipe-to-dismiss; queue tab stays active when selecting a song from the queue
|
|
- Lock screen media controls (Android / iOS via Media Session API)
|
|
- Gapless-style queue with prev/next, skip forward/back
|
|
- Scrobbling — plays are reported to Navidrome after 15 seconds of continuous playback
|
|
|
|
### Discovery
|
|
- iTunes / Last.fm integration — charts, global search, 30-second previews, similar artists, recommendations
|
|
- Spotify playlist importer — paste a Spotify playlist URL to preview and download all tracks, enriched with iTunes metadata and cover art
|
|
|
|
### Downloads (yt-dlp backend)
|
|
- Download individual tracks, full albums, or entire artists from YouTube / SoundCloud
|
|
- Spotify playlist importer downloads with iTunes-enriched metadata (album, year, track number, genre, cover art)
|
|
- Duplicate detection — skips tracks already present on the server
|
|
- Lyrics embedded into downloaded files (LRCLIB)
|
|
|
|
### Playlists
|
|
- Create, edit, and delete playlists
|
|
- Edit playlist name, description, cover art, and public/private toggle
|
|

|
### Audiobookshelf Integration
|
|

|
|

|
|

|
|
|
|
### App
|
|
- PWA — installable on Android / iOS / desktop, offline-capable via service worker
|
|

|
|
