Back when Sweetie was basically a spoiled, mean girl my muse song for her was When Your Evil by Voltaire. But as her muse grew and developed into the complex girl she is now, she doesn't really have a song muse. I've never been able to find one that's good enough. Sometimes some songs will be good for a certain moment, but I can't find one that fits her mood and situation at the same time.

Less specific, most of my characters don't have muse music. Maybe it's because I can't write very often while listening to something.
