That slipknot video is rediculous...I was a fan back in my angsty high school days and to be honest,this song doesn't sound like its anything new (like they're stuck in 2001). However, I like the fact that there are clean vocals in the song.
I also wish they would ditch the masks...just my opinion.

On the tooth tattoo...I just don't see the reason for one. Granted I like the artist's skill, I just don't see that it would become a fad. I have to admit, the Letterman and the Queen Elizabeth tooth are quite impressive.
