As an aside, I think YouTube Music is superior to Spotify in terms of music catalog.

You get "everything on Spotify" (high quality audio) plus the YouTube videos (eg mixes that are put up) in a battery-friendy player (possibility to go audio only on these videos). Of course minimizable with YT Premium.

I believe that the discoverability algo is much better with YouTube Music as well, which is important to me...

I pay ~$15/month (in my local currency) for YouTube Premium which also gives me the ad-free experience on YouTube.
