So Relic releasing their DOW2 soundtrack for free got me thinking about custom soundtracks. Bionic Commando is here soon, and i keep thinking about playing it with the Rearmed soundtrack. What i would love would be if the 360 or PS3 had a "copy soundtrack" option for games that choose to support that feature, that simply takes a set of tracks stored on the game disc and copies them over to the HD, so you can play them from your console whenever, or as a custom soundtrack for other games.

A lot of game soundtracks are split up into dozens of files per song, to let the music change dynamically along with the gameplay, so developers would have to choose to implement such a feature specifically for this purpose.

I think it'd be worthwhile though. For some games the music lives on beyond the gameplay.
