musical bitch

a person that constantly bitches about music that they don't like and is so arrogant/bigoted that they don't care to mention or acknowledge that the music they like is (also) considered shit or not very popular. An example would be someone that listens to hardcore bitching about metal.

Person 1:OMFG metal is SOOO shit!!
Person 2:Fuck off and listen to your hardcore musical bitch!
