In addition to songs from SaGa and Mana games, Square Enix pulled a track from Xenogears for Theatrhythm Final Fantasy Curtain Call. "Soaring the Skies," the music that plays when Maria boards Seibzehn and fights Nikolai is available in Japan as downloadable content. As a tribute to Xenogears, the song has Seibzehn in the background standing behind your party members.
Square Enix also went back to the origin of the Mana series, Final Fantasy Adventure in North America, and brought back "In Search of the Sacred Sword." Final Fantasy fans can also get "Primal Judgment" from Final Fantasy XIV: A Realm Reborn and the music from Cloud’s first mission in Final Fantasy VII.
