Video Games
Oh man, don't get me started... Half Life 2, Crysis, Call of Duty 4, World in Conflict, Forza Motorsport 2, Gran Turismo 5 Prologue, World of Warcrack, Rock Band, GTR Evolution. That's the stuff I can think off the top of my head that I've been playing lately. I play on PC, PS3 and Xbox 360. I like a bit of everything; Racing sims, shooters, RTS, fighting games... big time gamer here.
Music
Crowbar (favorite band for years now), Alice in Chains, Pantera, Godsmack, Zakk Wylde, Black Sabbath, Slayer, Manson, Down w/ Phil and Kirk and crew(not Syndrome of a Down, I can't stand them), Sepultura, AC/DC, Hendrix, Agents of Oblivion, Type O Negative...
Way too many bands/artists to name.
Lots of metal and rock, but I also love classical and opera. Vivaldi, Puccini, Beethoven, Tchaikovski...
I have never woken up without a song in my head.
