User blog comment:Tribellium/Prequel Storyline & Music Box System/@comment-1854594-20120722185739

If you're on Xbox (not sure if PS3 can do this as well) the music box is pointless. Anyone who has the Ressurection pack should have gotten a code to download the mp3s for all the songs and you can plug in a flash drive/mp3 player to your Xbox and have it play the music for you while you play the game.

Can't say I support the music box idea, even without the ability to play music through my Xbox. I like the easter eggs.
