Oh wow... music I use can range from industrial, oldies, goofy modern dance songs, pop, bellydance accompanyment, opera, classical, various movie soundtrack bits (the ones that are less recognizable, but still very lovely or inspiring, so I don't get the movie popping up in my head while I work), or soft instrumental depending on what it's needed for. I love my iPod so very, very much. I'll end up with playlists for books, characters, particular scenes. I particularly like making a mix that one of my modern fantasy characters or another would actually listen to. Sometimes this can be hilarious, and it almost always helps me get to know my character. For sword and sorcery style fantasy I tend to like Loreena McKennit quite a bit, for starters. I also have some Gregorian chant, medieval instrumental from the French courts, or sometimes I can get some kind of new age-y music to fit. If I currently needed more I would probably try to use Loreena McKennit's name in one of those "help me find songs like this" programs you can find (like the one attached to iTunes, if you use that, I forget the name). Of course, it always depends on the mood I want and the scene I'm specifically working on that sitting.
