bullet 4 my valentine has some good guitarring but i am not a huge fan of their music. Children of Bodom i listened to one of thier songs and couldnt understand it so i stopped listening to them :P
Korn is well known i just dont listen to them...i am thinking of DLing some Metallica.
Btw Sadistic...i dont count mine by song...i use torrents and download albums at a time, i have all staind albums, offspring albums, system of a down albums, and Mindless Self Indulgence albums...ther rest i have scattered albums, but for most of those bands i listed i practically have all of their music
