Mostly I like to focus on the music, but I do use it as a sort of motivator when I'm working on things like dishes, cleaning, or exercise.
Wherever I am, my music isn't more than an arms length or two away. :3
That's part of the reason I've been looking into a solar charging station for things like mp3 players and cell phones...at least then if we lose power I'll still be able to charge my gadgets. xD
