Remember the era of the "Hair Bands", and how any band that played heavy metal was labeled the same way? It was assumed that all of the musicians were nothing more than neanderthals that could play an instrument and had big, huge Aqua-Net enhanced hair. Even today metal bands seem pigeon holed and those beliefs seem to still have a white knuckled grip on the genre, but that is simply inaccurate.
You don't believe me, then take the time to listen to "The Worshyp".
