Switched to this app when they killed Play Music, app worked fine until one day I noticed out of the over 1000 songs I had in my library I was hearing the same 100 or so songs every day. Over 2/3 of my library was "unavailable" even though the songs definitely still exist. Only fix was to delete the song from my library and search and add it back and I'm not doing that for 800+ songs so I'm unsubbing and going back to Spotify as it's not worth keeping an active sub just for YouTube add removal.
