Who the fuck cares what music/ band someone likes, so what if it’s not the same band or genre you like. Get over yourself, people aren’t born to please you or anyone else. People have different tastes, what you might like is going to be different from what someone else likes. And another thing, stop hating on an artist or band they might not be important to you but they are to someone else. So just stop, stop criticizing others about what they like. Does it affect you? No. Enough is enough.
