While YouTube Music is still a clear regression from GPM, it's slowly catching up. Any year now it'll be good... But it seems it might already annoy you less than Spotify? Which is interesting, most people seem to believe Spotify is superior.
Did it stop mixing YouTube likes with music likes? Destroying my 'liked' music playlist was an unforgivable sin in my book. Fortunately I was able to get my old GPM info with Google Takeout before it went away, so I just scripted up a solution to recreate those likes on Spotify.
