Well, I'm using the SpriteWorld Sounds utility for my sound/music both. It works quite well take a listen to my uDG:

SpriteWorld of course is free source to look at. I'll mention again that SWSounds.c can trivially be taken out and used separately. My in-game music file needs to be looped a tad better, but the jump isn't too bad at all. I _think_ it's a lot less than other methods, especially QuickTime.
