Interesting. One of my many many complaints with YTMusic is that it does discovery very poorly. It fills any radio/discovery queue with one or two new songs followed by all the songs already on my playlists.

Other big complaints include no ability to prevent it from substantially using my cell data despite telling it to do everything over wifi. I've taken to just removing network permissions from the app unless I want to add something.

IMO you don’t need curation/algo - you need social network effect where you follow people who repost similar content you like. Your graph grows and if you don’t like something - cut them off. This is how soundcloud works.

I'm not using Youtube Music, just regular free Youtube with an ad blocker.
