It’s on eBay. Among soundtrack collectors this is known as an “FYC Promo” – a disc pressed and sent to members of the music branch of the Academy of Motion Picture Arts & Sciences “for your consideration” around Oscar time.
The track listing, according to the auction, is as follows:
Disc Game Intro
Rinzler vs. Sam
Quorra Saves Sam
Sam Plans Escape
End of Line
Flynn Drops In
Solar Sailer Alt.
Recovering the Disc
…which probably includes a lot of stuff that was on the official releases under “sexier” titles.
But on the off chance that there’s stuff that wasn’t on the official release anyway… well, as you can see, it will cost a few dollars to make that determination. Sorry, guys, $90-$120 is approximately $100-$130 more than I have at the moment.
