Side Effects

I went to a matinee screening of "Side Effects" last Tuesday and instantly thought that Thomas Newman's musical score would make a perfect soundtrack for my new novel "Frances" (yes, I have soundtracks for my novels; blame it on my obsessive love of film). Since then it's playing on repeat when I'm writing. It's amazing how fitting music can boost creativity and conjure up the right atmosphere. "Frances" will be a story combining demonic possession, evil kids and cats.

What kind of music do you listen to when writing/working? How does it help your creativity?
