When I made it, I envisioned a frozen wasteland, bereft of life. If you've ever played Super Metroid for the NES, you would recall that in the beginning, once you're on Zebes, and are headed for the morph ball, the music there is very subtle and simple, because there are no space pirates there yet. That's the same kind of feel I had in mind- an empty/creepy feeling for an area that is both icy, and not yet (or no longer) inhabited. So, simple and empty was what I actually was looking for.
