TIE Fighter has some really cool music (or at least the DOS versions have), made by legendary Michael Land, Peter McConnell, Clint Bajakian and, of course, John Williams. As it isn't quite as famous as the Monkey Island music (for example), there are not that many good recordings around, but I've found some cool stuff and also made two recordings myself. As my hoster is not fond of people storing mp3 files on their servers, I have zipped up my own and only give you the links to the others on iMuse Island.
