Which song do you listen when you're writing fanfics?(AU, plot, slash, etc.)

Back In Black, Smoke On The Water, and right now, Hero by Nickelback.

It depends on the mood. Sometimes its "Never Leave" by Seether, other its almost anything Marilyn Manson. Sometimes....it's a lot of sappy songs that make me meloncoly like "Here With Me" by Dido and "Only Time" by Enya. :)
