The game includes over 70 songs. There are at least five tracks for each Final Fantasy from the original to XIII, corresponding to a field, battle, event, opening and ending theme from each game. There are also extra themes that can be unlocked with Rythmia points and be played in special modes; and paid Downloadable Content. The game also borrows themes from past games for menus.
lots of songs.
each should have its own background.
