ZOMG, this. My dad's a big fan of Cookie Monster Metal, and it drives me up the wall.
I want some metal singers who can, y'know, sing and stuff, rather than just shouting incoherently into a microphone. Say what you will about the dude from Rammstein; even if he DOES sound like he exists on a diet of gravel and cigarettes, he IS singing, rather than just shouting.
I want to hear Jon Oliva actually singing about Spiderman, or something like that. It'd be the coolness.
