Eh - I'm a fan of Doom and Black metal, but some I'm not too keen on. I like music that I can listen to - music that is melodic in it's own way but still with that in-your-face heavyness that I crave. With some, some of the music is so manic and fast paced, it sounds like all the musicians in the band are doing they're own thing (Most of Cryptopsy is a good example) - where as bands like Chimaira, MH, 'knot etc, you can actually hear the riff they're playing.
Sock Man: It was "When Darkness Falls" that really made me buy the album, I heard it on some Metal Hammer free CD - it blew my head away when I heard it.
