For my taste Yt music has almost everything, but spotify hardly has half my playlist. I've found most of the music I listen to through youtube. So it's not suprising. But I'd wager that almost every song on spotify is uploaded to youtube as a video. Then it should be available on yt music unless they have flagged massive amounts of videos as not musical.
