@Suiseiseki @otso And from my limited experimentation it's not even good playlists, spotify gets a gew good tracks and then it keeps playing kind of related but not quite what I'd play, yt gets stuck in "loops" of the same ~10 tracks. Thank you but I'll stick with Jellyfin and my own playlists.
Inb4 Jellyfin is proprietary because it's built with .net iirc
