Not sure if this is yours, but mine was that it would often swap out my tracks for radio edits, even though I uploaded the original. I'm an adult, I bought this music, I don't need the kids' version. There's a built in feature you can use, "fix incorrect match," that would fix this only about half the time.
Oh right, it also capped the max size of playlists to 1000 songs for some reason.
Now it sounds like YouTube Music won't even let me listen while switching to another app, like a workout app, and won't let you turn off the screen without the music going out. Hard to believe.
Looking around, I'll be moving to musicolet I guess. Sounds like AIMP and BlackPlayer get good reviews too, but I really love the idea of an app that actually tries to limit the permissions it requests from you.
