@Mel-I am not blessed with either art or music. But several of my friends are, and having been dragged to the music block enough to listen to Bryony's re-working of this song or that song I
think (not trying to be snobby, I really do think

) I know what talent, and good writing, is.
As for Slipknot, it's the teenagers who think "Oh my God, they wear masks and chop up goats, they are so cool!" they like the image, not the music.
Yeah, I know Nirvana were popular. I grew up listening to Nirvana; my mother constantly played it (and Hawkwind) around my house. She still does, when I haven't stolen the CD
I prefer smaller, less known bands. The thing is, sensationalised bands (I've noticed) tend to crack up under expectations.
