Interesting that the reasons given here mostly also apply to game soundtracks as well, which is mostly what I listen to while coding. (Overclocked Remix has some great compilations if you are looking.)

I suspect game soundtracks differ from film soundtracks in that they're the backdrop to something that's still interactive, but I'm not sure how that comes into play.
