Right, but this is Youtube Music though.

I can play Cannibal Corpse without an account on a browser. What the hell are you listening to? lol

Well that’s a name I haven’t heard in a long time.

No, your phone doesn’t listen to you 24/7. With that out of the way, there are a number of places where youtube may have gotten that info. One possibility is that someone in your household looked up the movie and maybe checked if stuff ripped from netflix is indeed full HD. And since everyone in your family is using the same NAT IP, then it’s easy for youtube to target recommendations at everyone in that household.
