Substreamer switches to offline mode automatically when your server is unreachable. TUNED IN — SMART MIXES Personalised playlists powered by your listening history. Time-of-day mixes, deep cuts from similar artists, decade time machines, genre blends, favorites radio, and a custom mix builder — all generated from your own library, not an algorithm trained on someone else's taste. LISTENING ANALYTICS See your play history, top artists, albums, and songs, most active listening hours, activity heatmaps, and listening streaks. Scrobbles queue locally when you're offline and sync automatically when you reconnect. Exclude specific albums or artists so one-off plays don't skew your stats. LIBRARY MANAGEMENT Browse by album, artist, or playlist. List and grid views with alphabetical quick-scroll for large libraries. 5-star ratings and favorites sync with your server. Create and manage playlists, reorder tracks, or save your current queue as a new playlist. PLAYBACK Background playback with full lock screen and notification controls. Adjustable playback speed, shuffle, and repeat. Share albums or playlists with configurable links. BEAUTIFUL & PRIVATE Light, dark, and system themes with custom accent colors.
