I just rematch the destiny live trailer when one of the character ask for music from ghost "music. Something classical" and they fought with good music for a fighting scene. Would u want to have ghost play an action song for you of your choice during a raid or multiplayer? Want to have bungie to put some song on it or have them put something on the website to make your own custom playlist to send to your linked console? I would love to play action song in-game without having to use my iPod.
