Siansa on three phones: your listening year, the Home page with today's mix, and the now-playing screen

Siansa

Music player for Android

Plays your own music server (Navidrome, Jellyfin, Emby and other OpenSubsonic servers) and builds a fresh mix for the time of day, the weather or a mood you describe. Audiobooks and podcasts from Audiobookshelf play alongside.

  • Mixes made by sound, not by guesswork
  • Synced lyrics and gapless playback
  • Your library never leaves your server
