* [[https://www.youtube.com/watch?v=HIv_dEa_vrM "Musique pour la tristesse de Xion"]][[note]]literally "Music for the sadness of Xion"[[/note]], a melancholy variation on Kairi's theme that is quite fitting for the character.
** And here's the [[https://www.youtube.com/watch?v=UCH8O7kOSaY 1.5 HD Remix version]], which cranks the theme's awesomeness up.
** Someone actually decided to cover this song. And by cover, it's actually complete with original lyrics and some pretty good singers to boot. [[https://www.youtube.com/watch?v=U5aGEMqca4M Here you go!]]
** An [[https://www.youtube.com/watch?v=QV6Apkaborw orchestral remix]], emotional and epic enough to go toe-to-toe with the orchestral remix to "Simple and Clean".
* [[https://www.youtube.com/watch?v=PVDavId-9IU "Another Side -Battle Ver.-"]], the mix of "Another Side" used for the DoomedByCanon final boss battle that was first shown in the track's original appearance in the Final Mix version of ''Kingdom Hearts''.
* [[https://www.youtube.com/watch?v=ttZ7WKNroYE "Vector to the Heavens"]], Xion's final battle theme which is a remix of her character theme. The [[https://www.youtube.com/watch?v=AwK5nmzNMJc 1.5 HD Remix]] version makes it even better.
* The ''358/2 Days'' [[https://www.youtube.com/watch?v=3E-xPwnzdKQ version]] of "Dearly Beloved". Shimomura must really like playing with this one to see how much more awesome she can make it.
* [[https://www.youtube.com/watch?v=cyCNXueijXo "Secret of Neverland"]] and [[https://www.youtube.com/watch?v=gFX1wZ1TUFg Crossing to Neverland]], Neverland's themes in this game which are completely redone from the Neverland music in the previous games. It's a shame they didn't use it in ''Birth By Sleep''.
* Then there's [[https://www.youtube.com/watch?v=gt5D-1IaryQ "Critical Drive"]], one of the final battle themes in the game. While the [=KH2=] version, "Deep Drive", was all right, the ''358/2 Days'' version really brings out Roxas's and the player's drive to beat the mission.
* [[https://www.youtube.com/watch?v=wxVLK-hzbms "Mystic Moon"]], the remix of "Sacred Moon" that plays as Roxas escapes the Castle That Never Was, perfectly communicates the tension, fear, and uncertainty in Roxas's leaving of the Organization.
* The opening song, [[http://grooveshark.com/#!/s/Sanctuary/3WCOf4?src=5 "Sanctuary"]]. While it made its first appearance in ''Kingdom Hearts II'', the lyrics really fit with the Nobodies, especially Roxas.
* [[https://www.youtube.com/watch?v=ScGJEi11mx8 "Fight and Away"]] is a fantastic remix of the two boss themes, "Struggle Away" and "The Fight for my Friends", from ''Chain of Memories'' and makes any fight ten times more epic.
* The very melancholic yet beautiful [[https://www.youtube.com/watch?v=n38Cc0AcFBk "Missing You"]], debuts in ''Kingdom Hearts II'' but fits the theme and sadness in ''Days'' much better.
* [[https://www.youtube.com/watch?v=TEPJAbu1Y3o "At Dusk, I Will Think of You..."]] a sweet theme for the times Roxas, Xion, and Axel spend at the clock tower.
