Edit: Found this news blurb - "The Last Guardian Composer’s Choice PS4 Music App of the score featuring 19 tracks will be available separately at launch via the PlayStation Store. The soundtrack app supports both stereo and surround playback, and also allows users to export all the tracks as stereo MP3 files via a compatible USB drive. The soundtrack will also be available via iTunes at a later date."
