There's no such thing as bad music. Just some songs people don't prefer, I myself don't enjoy Gangnum style. I don't see how it became so big, everywhere I go on other sites I heard people bitching about party songs and hip hop saying it was trash, then they turn around and play Gangnum style. It's the same thing, it's a generic party song not really anything special(unless Christopher Daniels/Kazrian does it) except it's in Korean, which also provide the fact that those same people care not for lyrics. For all we know the lyrics could be insulting everyone who isn't Korean.
