That's part of the problem with YouTube Music. I tried to use it, but having music playlists clutter up my video playlists is pretty terrible, among other things.
I find it hard to justify paying for 2 music streaming services, so I cancelled Apple Music, because I'm paying for YouTube Music through Premium. However, I don't like it, so I'm back to manually managing a local music library in Apple's Music app. This is probably a better long-term approach than renting access to a music library on a monthly basis.
