The app is great and I prefer it over Spotify for the sole reason that it comes with YouTube premium. The player it self is actually pretty good and has "add to queue" and "play next" options. The only part that is truly frustrating is that some songs will just randomly become unavailable on YouTube music, sometimes half a creators playlist. For example Grimbeard, I listen to his music playlist a lot but a little more than half of his songs are just unavailable.
