Thanks for posting this.
For anyone who wants to play, I highly recommend the Stalker Complete mod (http://www.moddb.com/mods/stalker-complete-2009/downloads/stalker-complete-2009-14-exe-installer) - overhauls much of the game, improves just about everything.
And, here's a mp3 rip (http://www103.zippyshare.com/v/0V398R0T/file.html) of the WAVs.
