Kingdom Hearts Birth by Sleep & 358/2 Days Original Soundtrack

The Kingdom Hearts Birth by Sleep & 358/2 Days Original Soundtrack is the official soundtrack for Kingdom Hearts Birth by Sleep, Kingdom Hearts 358/2 Days, and Kingdom Hearts Re:coded. The soundtrack was released on February 2, 2011 in Japan. The 3-CD set is bundled with the soundtrack for Kingdom Hearts Re:coded, albeit not mentioned in the title. The soundtrack also contains additional tracks from Kingdom Hearts Birth by Sleep Final Mix, rather than on a separate CD, as was the case with Kingdom Hearts Final Mix - Additional Tracks.

Trivia

 * The music included from 358/2 Days and Re:coded is not from the game, rather arranged using instrument samples that are higher quality than the original DS games used.
 * Arranged versions of music from previous games in the series used in the 3 games are not part of the soundtrack release, and have never been released officially. This was highlighted when the Birth by Sleep version of "The Encounter" was used in Kingdom Hearts Melody of Memory.
