I tried out the iOS version of Disney Infinity today (a little stunted by the platform for me, but good nonetheless) and was surprised to hear "The Secret Swim", a musical piece from the Atlantis film, when using the Atlantean Sky. At first I thought this may have been added to the console versions via the February update, but after I had installed it the music on my PS3 version is still the same generic music it has always been.
Maybe this should be flagged up to the developers, since I (and probably many other people) would love to experience the Atlantean Sky with music from the film, let alone its best musical piece.
