I love this game by both the gameplay, the sound, and the music.   I did not purchase the Collector's Edition because they didn't have any within the area I live in; all they had was the normal edition.   However, I know there should be a way to extract the music files from the game I already have installed, I just want to know how to do it.

And, if it's wrong/illegal to do this, then please just ignore my request about this.  I'd think it would be legit sense I own the game (purchased it) and have it installed on my PC and all.  Heck, I did an extract for the Portal song "Still Alive", but that's a completely different process using a 3rd party Steam extracter.
