Er...ok so all the bands in the poll absolutely suck, except possibly for Slayer, but their material is so samey and boring that I can't deal with them for too long.
I can't believe that Metallica are actually popular in this day and age, what with their last 4 or so albums being absolutely terrible, ESPECIALLY St. Anger. You know, the album where they didn't let Kirk play any solos because they wanted to sell out that tiny little extra bit (and then when they let him play them again on his new album, he's forgotten how to and ends up churning out some god awful structureless mess for the entire album). Work it out, Metallica suck!
As I Lay Dying, Byzantine, Chimaira, DevilDriver, The Haunted, Human Abstract, Killswitch Engage, Lamb of God, Machine Head, Parkway Drive, Protest the Hero, SikTh and of course the mighty Unearth are all better than every band anyone on here has mentioned (especially Protest the Hero and Unearth).
