Thanks, good info. I'll look into the container thing. I just refuse the browser cookies as a default. So I don't get any recommendations on the browser.
I'm same as you with music, I have very specific tastes, to the point that my best friends don't bother recommending anything to me anymore lol. Or if they do, they say "I know you probably wont like this but I've been listening to __________ recently" haha. I'll see if I can find motivation to let youtube recommend something for me. I did use YouTube Music with Morphe for about half a year and.... it wasn't very good. I even did the whole "don't recommend this" dance, but it still kept recommending the artist, just different albums/songs. But maybe it was a case of not using it enough.
