What I listen to when i'm working on my comic is way different than when I work on my novel.
Cole - I listen to the scores from the movies Edward Scissorhands, Twister and Nightmare on Elm Stree (the remake).
Megami Shiizun - I listen to general instrumental when I'm on drawing mode, but if I'm writing any of it. I have the album of Legends by Two Steps from Hell and the scores of animated features.
I don't listen to anything with words when i'm writing, it's too distracting.
