Being a big metalhead myself, I have to toss in Demolition Racer: No Exit for the metal list. I think some of the Twisted Metal series had dominantly "metal" tracks as well.
Aside from the list, I tend to gravitate toward the slow and heavy stuff. I only really care for Black Sabbath's earlier stuff like their "Paranoid" album. I absolutely recommend Pentagram to anyone who enjoys Sabbath, but New Orlean's Thou is my absolute favorite sludge/doom band. I used to be really into grindcore, but I only really pull Pig Destroyer and Agoraphobic Nosebleed off the shelves these days. I like some Crust Punk, but it tends to end up sounding the same after a while.
Here's my usual playlist:
Black Cobra (Hardcore-influenced Sludge)
This Runs On Blood (weirdest Hardcore I have ever heard)
Thou (heaviest band in recent years)
EyeHateGod (Sludge masters)
Whores. (these guys are great)
Kowloon Walled City (Sludge and damned good)
SubRosa (Experimental Doom w/ violins)
Batillus (NY Sludge Doom)
Pig Destroyer (Thrashy Grindcore)
Agoraphobic Nosebleed (a Grindcore Drum Machinegun and weird as hell)
Fister (Saint Louis Doom Face-wreckers)
Mammoth Grinder (a strange mix of Grindcore, Hardcore, Sludge, D-beat.... all awesome)
High On Fire (Celtic Frost-tinged Sludge)
The Haunted (Post-Thrash w/ a Death Metal edge)
At The Gates (Death Metal)
The Faceless (Tech Death)
Dismember (Death Metal)
I'll admit that I have a huge soft spot for Radiohead.
YEAH. I SAID IT.
