I received my Xbox 360 version copy this morning, no actual CD came with it... Only a code to download the music. The album cover was embedded in the MP3s.

The PS3 limited has got a CD? Damn!
If what bugged you was the folder in which I putted it, I sincerely apologize, that's the way I label all soundtracks that I've got by owning also the game disc
