What music do you listen to when doing what you enjoy, and how does it affect your artistic ability?

For example, when I'm writing an RP fight, I listen to stuff by Bullet Fot My Valentine, Avenged Sevenfold, stuff like that. When I'm feeling lonely, I listen to stuff like Nickelback(some of their stuf is pretty decent). When I just want to vent my anger, it's time for Metallica, Slayer, In Flames, Disturbed, stuff like that.
