 Mopidy is an extensible music server written in Python. It's mostly designed to provide an easy hardware jukebox for Spotify or whatever crappy web service you want to use. I use it for Bandcamp, mainly. There is [[id:c75d20e6-8888-4c5a-ac97-5997e2f1c711][NixOS]] module support for it so I enable it in [[id:cce/my_nixos_configuration][My NixOS configuration]]. I want to use it for Youtube Music but this doesn't work reliably because they're fucking cops, though...
