* All three of the game's remixes from ''VideoGame/TheWorldEndsWithYou'': [[https://www.youtube.com/watch?v=C_cJrbCYk9c "Twister"]], [[https://www.youtube.com/watch?v=QJbszmEqI1E "Calling"]], and [[https://www.youtube.com/watch?v=J5oQP6mVcjM "Someday"]]. "Someday" in particular works surprisingly well as a slower-paced theme for cutscenes, rather than a fast-paced theme for boss battles.
* As the tradition goes, a new and amazing version of [[https://www.youtube.com/watch?v=k5pOhEJs08A Dearly Beloved]] just as beautiful as all the others. And [[https://www.youtube.com/watch?v=LowlxH10dRs another new version]] is played when Sora and Riku save Mickey in Symphony of Sorcery. The version from ''VideoGame/KingdomHeartsII'' plays when Riku resolves to rescue Sora, who had fallen into a comatose state of sleep, and Lea promises to help him if Riku himself is in danger.
* [[https://www.youtube.com/watch?v=L1G3pqNJh2U Xigbar's own leitmotif, debuting in this game.]] It's the Organization XIII theme, only with a faster rhythm - a waltz, to be correct - and a creepy violin theme playing underneath. This is meant to invoke an unpleasant effect[[note]]the same effect as, for example, [[VideoGame/TheLegendOfZeldaMajorasMask The Third Day in Clock Town]][[/note]]; and while it'd be spoileriffic to say why, this theme fits Xigbar and Braig perfectly, summing up his prominent role in the formation of the rest of the Organization.
* [[https://www.youtube.com/watch?v=h-xbOua5CyU Link to All]] is very upbeat theme that very well emphasizes Sora's ability to link so many hearts.
* As usual, the game features several awesome remixes of "Destati", including the [[https://www.youtube.com/watch?v=DFU_nm7MTAE two]] [[https://www.youtube.com/watch?v=3krHHAx0loY themes]] of Ansem, the [[https://www.youtube.com/watch?v=enPC9CZVb68 last Dive]] into Sora's heart, and the [[https://www.youtube.com/watch?v=LsFC6h59rc8 theme of the final battle]] with Armored Ventus Nightmare. For added awesome, the final battle theme is orchestrated in a style reminiscent of Vanitas's battle theme.
* [[https://www.youtube.com/watch?v=ad4_AwjX_D0 Sora's theme]] gets a remake that still keeps on rolling.
* [[https://www.youtube.com/watch?v=_DetmBQCSas Shimomura still knows how to make great credit music.]]
* [[https://www.youtube.com/watch?v=pb8wmjW1xsk "Distant From You"]] has a sad and nostalgic theme to it. Perfectly suiting the scene it plays in: Meeting Xion and Namine.
* [[https://www.youtube.com/watch?v=7-qxLEUdSLA "Broken Reality"]] starts cheery, but slowly descends into a song that personifies a very childish madness.
* [[https://www.youtube.com/watch?v=4yA6CPWR3Hw Traverse Town's new theme, "Traverse In Trance"]], sounds really sweet and relaxed. Even more than the original.
** [[https://www.youtube.com/watch?v=0tKe3HZfwcQ "Hand To Hand"]], its battle theme, is a really sweet remix of "Hand In Hand"!
* While it may not be a Disney-related song, [[https://www.youtube.com/watch?v=d6uuMRfM8Tc "La Cloche"]] and [[https://www.youtube.com/watch?v=wQVTpi6Mdek "Le Sanctuaire"]] are very ominous and suiting of [[WesternAnimation/TheHunchbackOfNotreDameDisney one of the darkest Disney movies]].
* [[https://www.youtube.com/watch?v=BimeQw6xDxI "Sweet Spirits"]] is sugary elevator music.
* [[https://www.youtube.com/watch?v=x76CZIUmDKM "Majestic Wings"]] is pretty awesome for a soaring battle theme against a monstrous gargoyle.
* [[https://www.youtube.com/watch?v=uHnv9I_qG4Y "Ever After"]] is a brighter "Distant From You".
* [[https://www.youtube.com/watch?v=3qnQpjmp2Dc "Rinzler Recompiled"]], a sweeping orchestral powerhouse that sounds like it was pulled straight out of ''VideoGame/MassEffect''. It's also a major TearJerker given ''who'' the boss really is.
* [[https://www.youtube.com/watch?v=BzFykKvUNyQ "UNTAMABLE"]], the most recurring Dream Eater boss themes, gives off a fun fair vibe, inviting you to enjoy the fight, while being fairly epic! This is in contrast to a good part of the other KH boss themes which are usually ominous and foreboding, while being epic.
* [[https://www.youtube.com/watch?v=yw7nliZc5uc Ice-Hot Lobster]], like many Dream Eater boss themes, invites you to just enjoy the fight and have fun!
* [[https://www.youtube.com/watch?v=2KKKM9qOW8E Gigabyte Mantis]] gives a techno feel to the usual Dream Eater music, and works you up to excitement as you battle the boss!
* While Chernabog kept "Night On Bald Mountain" as his boss theme in the international and Final Mix of ''Kingdom Hearts'', some argue that the version used is pretty much inferior to the original. Thankfully, 3D [[https://www.youtube.com/watch?v=AvMZPyWEHKw remade it into something much more awesome to listen too]], and it makes the fight ten times more epic!
* "[[https://www.youtube.com/watch?v=56tVRGsZuy4 L'Apprenti Sorcier]]", for those who appreciate the classics.
* [[https://www.youtube.com/watch?v=6ODAH1gBqyE "All For One"]], Country of the Musketeers' battle theme, is very energetic and cheery. The playful and peppy runs are what really sell the piece.
** [[https://www.youtube.com/watch?v=UVZ1wUAWhbU "One For All"]], its field theme, is similarly energetic and cheery, but in a way more fitting of running around and exploring, rather than battling.
* [[https://www.youtube.com/watch?v=UHOrW6sUKDQ "L'Impeto Oscuro"]], a truly epic remix of Dark Impetus that plays during the semifinal battle against [[TimeMaster Young Xehanort]], the familiar music making for a startling reveal that you're fighting the [[VideoGame/KingdomHeartsBirthBySleep last game]]'s {{Superboss}}.
* [[https://www.youtube.com/watch?v=bM1MGnV_PZ4 "L'Oscurita dell'Ignoto"]] is a truly amazing rearrangement of Darkness of the Unknown. The violin gives off a very ominous, urgent vibe which really suits the fact that it plays during the fight that shatters Sora's heart.
* There's also [[https://www.youtube.com/watch?v=DFU_nm7MTAE "L'Eminenza Oscura"]], the new battle theme of Ansem, Seeker of Darkness. Interestingly, it's what's ''missing'' from the song that makes it creepier than previous remixes. It starts off much like the first game's final boss theme, but then shifts into part of "Dismiss", the song from Aqua's fight with Terranort. Except ''[[FridgeHorror Terra's Theme is missing from this part of the song]]''. There is also the [[https://www.youtube.com/watch?v=3krHHAx0loY second part]] of the song which plays during Ansem's second phase, though with less emphasis on the "Dismiss" part of the song.
* [[https://www.youtube.com/watch?v=peIwhfDEH5g "The Dream"]], a soothing playful melody that calms your soul.
* The falling synths and sinister strings of [[https://www.youtube.com/watch?v=lpqxSW1zF9A "The Nightmare"]] create a profoundly unsettling atmosphere befitting its title and the [[MindScrew scenes in which it plays]].
* [[https://www.youtube.com/watch?v=EcWzfvD1zuY "Sacred Distance"]], the haunting theme of The World That Never Was. If you listen closely, you'll notice that one part is set to a slowed rhythm of the main choir motif in "Sacred Moon".
* [[https://www.youtube.com/watch?v=YvSf5HHhfH4 "Prankster's Party"]] is very energetic, and becomes just beautiful once the violin kicks in.
* Deep Drive's remix, [[https://www.youtube.com/watch?v=Nwymn3QGdcE "Deep Drop"]]. One part of this theme even includes a subtle remix of "Another Side".
* [[https://www.youtube.com/watch?v=RWF-lcxdZxw "Xehanort -The Early Years-"]], aka Young Xehanort's Theme. It sounds like a mix of [[VideoGame/KingdomHeartsBirthBySleep Xehanort's Theme]] and [[WesternAnimation/CourageTheCowardlyDog Katz motif]].
* [[https://www.youtube.com/watch?v=9PpyZKOtbDg "Shaded Truths"]], one of the suspense themes. Originally from ''VideoGame/KingdomHeartsBirthBySleep'', though it seems to be used more frequently in ''[=KH3D=]'' than it was in ''KH:BBS''.
* The normal fantasy party-like Dive theme [[https://www.youtube.com/watch?v=D0LoeILDSv4 "Storm Diver"]], and the boss Dive theme [[https://www.youtube.com/watch?v=tLdUXHYvXdI "Wild Blue"]].
* For fans of the classics, listening to [[https://www.youtube.com/watch?v=o6R6thWee6g The Nutcracker Suite]] and [[https://www.youtube.com/watch?v=zK1D-PRlSxQ the "Pastoral" Symphony]] throughout your whole trip in "Symphony of Sorcery" is both very calming and awesome. Especially since it continues even when you enter battle.
* [[https://www.youtube.com/watch?v=p2eUgF8Kf-0 "The Dread of Night"]], the dark and intense battle theme for Anti-Black Coat Nightmare. It drives the seriousness of the moment and puts you on edge.
* [[https://www.youtube.com/watch?v=ok7qtbbcz1g "Dream Eaters"]]. Riku reaches the Brink of Despair and can't get to Sora and all seems hopeless...then the spirits, Sora's Meow Wow and his own Komory Bat, appear and this music starts.
