I can't multi music, i mean, depending on what's happening I may change songs. But I'm a very one song kinda guy, PERHAPS, rarely, two.

I use somber violin music to keep me focused, paced, and relaxed. Which helps me refrain from just blowing shit up. That's what I use metal for.
Action scenes are typically a more upbeat song, or violin, but not too heavy. Chaos, death, and destruction are where the heavy metals, death metals, etc. come in.

I can't really do anything with words, as I tend to start listening and stop focusing on writing. And hip hop is just too sporadic, it plays with my emotions! XD

I actually use epic orchestra for big action-esque scenes.
