Nirvana is awesome!!
But here is my 2 cents on this topic: I liked Creed... when i was like 7. Now, they don't hold up at all. I got my Sabbath, Trivium, Disturbed, what have you.
As for Limp Bizkit (stupid name IMO) is a guilty pleasure. For some reason, i turn Rollin' and Break Stuff on, but then i want to turn it off again because Durst can't rhyme worth a crap. He made a whole new level of suck, and only the Jonas Bros and rappers can are there to keep him company.
