[Raises hand] I've been paying for a family music plan for years now. YouTube Premium was always just bundled with it. If they ever stopped the bundling I'd hop back over to Spotify.
I pay 6$ using a student discount for YouTube premium because I like watching YouTube on my android TV and I can't use ad blocker there. In fact I've been using it for so long that it actually shocks me when I see someone open YouTube and an ad pops up it feels weird
