FWIW, YouTube premium is one of my most worthwhile family subscriptions.

Anytime I use YT on a browser/profile that I'm not logged into, it's so jarring that I immediately fix it.

Edit: I dumped Spotify for YT music. I thought I liked Spotify better, though, so I tried again recently, and it turns out I didn't, so now I get YT and music for not much more than just Spotify. Definitely worth it in that context.
