Rap lyrics generally aren't awe inspiring either.
Honestly, do you know what the fuck you are talking about? Or are you just generalizing the genre by 50 Cent and Eminem? There are plenty of rap/hip hop artists who actually have quite insightful lyrics. Those 'gangstas' when they aren't fucking bitches and rapping about murdering one another, actually can be quite insightful and articulate. But I'm sure none of you would like to acknowledge that because it would only ruin your pre-conceived notions about it. I mean, these guys haven't been able to write a masterpiece like Janie's Got A Gun, but give them time...they could maybe reach that plateau.
And I'm sure a fan of metal can come out and point some profound meaning to the screaming.
It's stupid to advocate rap and defend it from naysayers while at the same time dismissing another form of music.
Why can't we all just get along and enjoy Nu Metal?
