I'm pretty new to metal music, but so far I really like

Lamb of God
Machine Head
Cradle of Filth
Amon Amarth
Behemoth
Cannibal Corpse
Nile
Dying Fetus
Carpathian Forrest

all seems somewhat death metal orientented. Have a look into the swedish death metal scene. Listen to Entombed, Dismember, Merciless and At the gates. Should be decent starting points for you.

Well you're obviously new, so I'd just start by saying you should probably lurk for a bit more before posting... and read the stickies first.

Anyway, that list is pretty diverse so I'd just suggest looking at other recommendation threads around here or the "albums this year that you liked" thread in metal discussion to get a handle on what kinda stuff you're looking for. And as you're new to metal you might want to start with the classics; Metallica, Slayer, Death, Morbid Angel, Mayhem, Bathory, Iron Maiden, Sepultura etc. etc. You've got a long journey ahead!

You could start by looking at all the similar artists on all the pages of the ones you mentionned, it will get you started. Also, check the many help threads we have. I don't allow "rec me everything I might like while I'm playing WoW" threads, metal is more rewarding when you find bands on your own.
