Worst vocal performances ever?

Alexi Laiho Rocks!!

he is a sick guitarist, and his vocals rule, and fit so well, his style is awesome
 
I'm the best singer ever. No I'm the most terrible but there's a fine line. There is a fine line because you can be so bad that it's good. However I don't think that's quite me. I'm just bad.

I hate Alexi as a guitarist and vocalist and songwriter. I appreciate his technical ability at guitar but that is all. Being able to play fast isn't everything.
