If there is music in the game, I'm assuming the files are in the game folders somewhere, but I figured I'd also try to dig up what I could:

From the composer's website: http://billbrownmusic.com/music_horror.php#clive

General YouTube search

http://gh.ffshrine.org/soundtracks/4888

As an interesting side note, much of Undying's soundtrack consists of reused tracks from the Jurassic Park game Trespasser.

I'd love to have the soundtrack of the game, too. I don't like gathering them around and I think the audio quality would be way better this way.
