This is just a little recommendation to players who are in to changing the in-game music. If you haven't played the short and excellent Braid, it has a soundtrack worth hearing. You might find some of the tracks violate the theme. That wasn't a problem for me as I wasn't into some of the default music, and so was used to the idea of removing/replacing some.
For a feel of it:

I like "Revelations 9-6", the chanting really does it for me. If anyone knows of something else like that, I'd be eager to hear it. I don't usually listen to that kind of music, but in AIW it's the combination with the space/technology theme. :)
Oh, plus a random one from a flash game called Rebuild 2 that has worked as BGM for me in AIW.
