"New Battle!!!" is the regular battle theme in the game, sounding like a mixture of Torna's battle theme and Future Connected's battle theme, while sounding overtly original in its own right, as well as being very catchy.
"Cent-Omnia Region" is an epic, sweeping theme for the Aurora Shelf area like its predecessors in Gaur Plain and Gormott, both of which are sampled in this music track proper. After the more ambient themes of 3's areas, Aurora Shelf's theme does nicely to bridge 3's musical style with that of the previous two games.
"Black Mountains - Valak Mountain" and "Black Mountains - Prison Island" are the themes that play respectively for the Valak Mountain and Prison Island sections of the Black Mountains, and make for one hell of a theme for the expansion's final dungeon, and by extension, the final dungeon theme of the "Klaus saga". Taking notes and motifs from the original Prison Island theme and the World Tree theme, it's the perfect song to accompany the climb up the Black Mountains to Prison Island, and to mark the final dungeon of the "Klaus saga".
"Redeem the Future" is the final boss theme, and is heavily inspired by "Zanza the Divine" and its inspiration "Godsibb". The first half starts off rather slow, quiet and orchestral like the first half of Z's theme while the second half becomes much more fervent, showing the intensity of the fight. In fact, it's so awesome that the Chain Attack does not interrupt the song, unlike it does for every other song in the game.
"Time to Fight!" makes its grand return for the battles in the area surrounding or leading to Colony 9, adding to the overall finality of Future Redeemed by bringing it back to the very first battle theme heard in the series.
