If you got FS2 from GOG.com, you probably downloaded the soundtrack as well. You then noted that the soundtrack was nothing more than the music extracted directly from the game, uncombined, and not terribly appealing to listen to.
...Or you cracked open the VPs to get the music. The result was then still the same...
Fortunately because of the efforts of Nix, we have most of the high-quality versions of the music from FreeSpace and FreeSpace 2... As well as many extras. What I would like to suggest is a community project to properly compile the pieces into coherent tracks. Anyone can do this with a free program like Audacity - I'm doing this right now, actually. However, I ask for collaboration as I'd like to think that by having several more experienced people than just myself working on this we could compile the tracks in such a manner that they'd sound as close to perfect as possible when compiled. After we're done, we can then simply upload the results to FSmods in .mp3 format. That way, everyone can have access to this music.
...And you'd never have to ask for a properly compiled set of the soundtrack with someone just telling you, "do it yourself" again. Ever.

That said, is there anyone on the board who'd be willing to help with this?
