POLL: WHAT DO YOU THINK OF THE SCREAMING VOCAL STYLE IN METAL?

This one has sure got you guys fired up in the comments sections, so let’s take it to the masses. I can’t say with certainty when the screaming vocal style was first introduced to metal, but I’m guessing it happened some time in the mid-late ’80s. By the early ’90s underground faves like Carcass embraced the technique, but it didn’t become acceptable in the mainstream until bands like Faith No More and the Deftones started screaming into their microphones with reckless abandon. Now you’ve got dudes claiming that anything with clean singing isn’t real metal. What do you guys think?
