All Quiet on the Writing Front or A Time to Rock

I find that I do my best writing with some tunes in the background. Further, it seems like what I am listening to can even affect my writing. It struck me that I could be in a small minority. Do you write with music in the background or do you need everything quiet? If you do write to music, what music have you found influences you? When I was writing "Colette" I was listening mostly to a group called, "The Jim Yoshii Pile Up." Their tunes are very melancholy and the book is a real exploration into melancholy thoughts and feelings.
