I cannot agree more. In my opinion it's the only music platform that hasn't been entirely captured by the mainstream record labels. I get all kinds of cool DIY bands recommended through it. I got more good recommendations from using it in a couple of hours than I got in the last few years via Spotify.
What’s great about YouTube Music is that it includes user uploads, meaning that you get tracks (e.g. video game music) and versions/recordings of tracks (like old 12" versions and remixes, or live recordings) that you are unlikely to get on a purely commercially-sourced music service.
