I've been asked not to link to the place I bought this from since they are in very short supply (there were only a few left when I placed my order). However, a quick Google search for "WarGames soundtrack CD" should turn up something useful - if there are any remaining.

Even though this was an officially sanctioned CD, it was obviously meant to be a limited-run production. The jewel case inserts are just color photocopies, and are completely lacking in liner notes. But if you do happen to find one of these for sale - this is a manufactured CD - not something just burned to a CD-R. If someone offers you one burned onto a CD-R, then it is almost certainly a bootleg.
