Melarka

Melarka is a free, open-source music server you run at home (one Docker container). Songs come from your own music folders, which it never modifies, or from YouTube: search, download a song or a whole playlist, or follow channels and let new episodes download by themselves.

Everyone in the household gets their own account with favorites, playlists, personal radio, nightly recommendations and synced lyrics (anyone can fix lyrics that run early or late). It streams the original file or transcodes to AAC on the fly.

The native iPhone and Android apps play in the background with lock-screen and car controls, gapless transitions and a sleep timer, keep an offline cache of your favorites, and can start your favorites by themselves when the phone connects to the car over Bluetooth, showing the current lyric line on the car display. A web app works in any browser and installs to the home screen.

Interface languages: English, Simplified and Traditional Chinese, Swedish.
