Band Basher

A person who critisizes bands that he/she does not like, simply because they dislike the music, so to them the band is therefore crap as a whole, regardless of what anyone else says or how highly revered the band actually are.

Person 1: "Oueen suck they're so overrated, whoever hailed Freddie Mercury as a rock legend wasn't right in the head."
Person 2: "You're such a band basher, just because you don't like them doesn't mean they suck."
