My choices of music...
Numetal & Metalcore: Atreyu, Dillinger Escape Plan, DownTheSun, SkyCameFalling (<3), Zao, Caliban, System Of A Down, Spineshank, As I Lay Dying, Hatebreed (one song, Perseverance. The rest of their shit sounds the exact fucking same), Alove For Enemies, Converge, Curlupanddie, In Dying Days, Lollipop Lust Kill, Hopesfall, Ill Nino, Korn (some stuff), Mudvayne, Slipknot, Rob Zombie, Nothingface, Slaves On Dope, Static-X...just to name a few.
Rap: Eminem. That's really it. His lyrics just motivate me in a lot of songs.
Techno: Dark Soho. If anyone likes techno, which not most do, download his song called Combustion. And Aggressive. Both get me fuckin' pumped.
