You like what?! It's over!
So, I've seen that other thread: does music taste really matter (in a partner)? Some say yes, some say no.
Let's ask the same question in a different way: have you ever rejected somebody because of (among other things, I guess) their music taste?
It doesn't need to be a potential bf/gf, also friends. For example, I knew this girl, and we got along and everything, but God, did she listen to some serious shit. Long story short, we're still friends, but I try to avoid parties and clubbing with her, 'cos I really find her taste depressing.
Been there, done that?
