There is a lot I haven't heard of either, but there are some great records on there.My number 1 made the list(The Dillinger Escape Plan) and two more of my top 10 are present(Intronaut,High On Fire) I disagree with having Fear Factory and Kylesa on there those were the two records I was most dissapointed with this year. The lack of Overkill,Landmine Marathon and Howl is a bit dissapointing. All in all, pretty good list.
I am with cool Maiden being absent. Let's just I did a rough draft of my list today and I am going to get flamed horribly at the postion is on my list
