The 3-CD set is bundled with the soundtrack for Kingdom Hearts Re:coded, although not mentioned in the title. The soundtrack also contains additional tracks from Kingdom Hearts Birth by Sleep Final Mix, rather than their being released on a separate CD, as was the case with Kingdom Hearts Final Mix. Discs one and two contain tracks from Kingdom Hearts Birth by Sleep, while tracks 1 to 13 on disc three are music from Kingdom Hearts 358/2 Days, tracks 14 to 20 are from Kingdom Hearts Re:coded, and tracks 21 to 27 are from Kingdom Hearts Birth by Sleep: Final Mix. Tracks from Kingdom Hearts 358/2 Days and Kingdom Hearts Re:coded are now in pure orchestrated form, instead of being digitized, as they are in the original game releases.
