Heavy Metal is my favorite genre of music
Slipknot's released a few good songs, but as a whole I think they're pretty average, I prefer bands Like Megadeth, Iron Maiden Judas Priest, Black Sabbath, Pantera, Amon Amarth, and Obituary.
Also, slipknot isn't death metal, they're nu metal EDIT:Ok, my bad, they USED to be Nu metal
