It's a good thing all they did was look at the popular, mainstream vocalists. They also didn't even factor in actual singing ability, just how high or low they ended up on a recording.
I still really like the vocalist, and one particular album of theirs, but no way in hell would they even make my top 20, or possibly even 30.

The sad thing is, those who we all know to always make the top five or ten spots aren't even anywhere to be found on that list. But it also doesn't say "metal vocalist" either.
