It's interesting how nu-metal guys said that they didn't want to be so dark and serious like 'typical' metal, and wanted to have fun too. I think that this is the main separator between the good and the bad in music. Bad music is written specifically for an audience to party to, socialize, and not think. It's music to reinforce their own vapidity. Whereas really good music creates sonic spaces for the mind and senses to explore and become immersed within. Listening to really good Black Metal is like being transported into another world. Nu Metal celebrated surface qualities and was a dead end, which is analogous with ending a drunken party in the bathroom, refunding out the mouth the day's meals into the toilet.
