Moghouse Jukebox..I support this idea sooo much.

Even for in-game music, perhaps make it so tracks in game that you haven't yet reached arent available, until you've experienced the area or the event itself, then that audio file and the cutscenes in the unending journal become availble at the same time. Granted, I spend a majority of the time with in game audio off and listening to Pandora, simply because the ingame music has lost its novelty to me after hearing it for so long. So there will come a time when I will turn 2.0's music off and return to Pandora, but being able to return to my residence and fire up the jukebox and listen to a particular series of tracks that I adore would be a welcomed treat.
