I understand that, but more of when people discredit any music just because of the genre label attached to it. I know I personally do it to country, but that’s because I’ve never heard a country song I like. But I still try to be open. But there are people I know who think that rap and pop music are the only good types of music.
What makes me more angry though is people who think metal music is all screaming. I have heard metal with good melodies and harmonies, it’s not uncommon.
