what I want is a jellyfin client on my raspberry pi, that can be controlled from my phone, I know mpd with mopidy can do this but it doesn't support liked songs and albums
I am running LibreElec/KODI on a Pi4 client using the IOS KODI remote app. Use the jellycon KODI addon and don't manually add any media in KODI. Let the jellyfin addon do all the media organizing.
