Another handy tip when you're running low on batteries, and you just have to hear that one last song is to turn it off, disable the shock protection, ESP or whatever, and turn it back on. This usually will give you enough time to listen to another song or three. I've also been known to pop in the AAA from my pager, wad up some tin foil (what? you don't carry tin foil on your person at all times? And you CALL YOURSELF A GEEK??) and stick it in there.
