 The official soundtrack of the game, The World Ends with You Original Soundtrack (すばらしきこのせかい ORIGINAL SOUNDTRACK, Subarashiki Kono Sekai Original Soundtrack, meaning "It's a Wonderful World Original Soundtrack") was released in Japan on August 22, 2007 and is on sale in most English-language iTunes Stores. This release, however, does not include the four tracks unique to localizations outside Japan and is simply a digital version of the Japanese soundtrack. Three of the tracks, "Someday", "Calling" and "Twister", were later remixed for the 2012 Nintendo 3DS title, Kingdom Hearts 3D: Dream Drop Distance. "Calling" and "Twister" were also remixed for downloadable tracks for Theatrhythm Final Fantasy: Curtain Call.
