So, I'm considering upgrading my normal digital version to CE, but I can't find anywhere that lists what's actually included. Is the digital upgrade only the in-game items? Those are nice and all, but I'm mostly trying to figure out if it comes with the soundtrack, or if that's ONLY for physical or new purchases.

Again, this is specifically asking about getting the soundtrack with a digital upgrade. Can anybody who has upgraded clue me in here? It would be much appreciated.
