I've not heard of a soundtrack release for this movie, however, most of the music used is available already. There are pieces of classical music used throughout (I can't remember what, check the DVD if you have it, the end credits should list the tracks).

What I can confirm is that a few tracks from Jean-Michel-Jarre's Oxygene album were used. Buy that CD and you've got much of the soundtrack. I recommend the remastered CD!

It's a great movie!
