The music of FINAL FANTASY RESONANCE is composed and arranged by Elements Garden, the composer group led by Noriyasu Agematsu. The group carries the same composer lineage as FINAL FANTASY BRAVE EXVIUS, the mobile game this title rebuilds, which keeps the score's identity continuous between the two.
Composers
Square Enix's Japanese edition material credits five composers on the score, not one. Noriyasu Agematsu is joined by Seima Kondo, Ryota Tomaru, Junpei Fujita, and Hitoshi Fujima, and the credit line covers the soundtrack as a whole rather than splitting it by track. The Japanese credit is the first-party form; the English spellings used here are the romanizations that English-language coverage of the announcement carried, since Square Enix had published no official English credit list as of October 23, 2026.
Returning and New Music
The soundtrack brings back music from the mobile game and adds 33 newly recorded tracks on top of it. Boss themes lean on the returning side of that split: they reuse melodies that players of the original will recognize, reframed for the new game's battles. Elements Garden handles both halves, so the new recordings and the returning pieces share one arranging hand. Staffing details sit on the development and staff page.
Image Song
Square Enix released a final trailer on September 17, 2026, the opening day of Tokyo Game Show 2026. The Japanese final trailer uses "INSIDE" by the solo artist WurtS as its image song, and Square Enix's announcement adds that the song is on WurtS's first mini album, SPARK, which was released on October 21, 2026. The shorter English cut released the same day, titled Tokyo Game Show Trailer, does not credit an image song in its descriptions. The announcement presents "INSIDE" as the trailer's image song and does not say whether it is also used in the game itself.

Soundtrack Release
A physical Original Soundtrack CD album collecting 120 tracks from the game ships inside the Collector's Edition's Collector's Goods Box. Square Enix has confirmed the CD will also be sold as a standalone product, on October 28, 2026, six days after the game, which makes the Collector's Edition the earliest way to own the album.
Square Enix's edition material now states the figure directly in both English and Japanese: the Collector's Edition includes a comprehensive soundtrack CD album with a total of 120 tracks from the game, and Japanese material adds that it ships ahead of general release. That makes the album the first published measure of the score's overall size.
The album is one of four physical items in the Collector's Edition goods box; the rest are covered on Editions and Pre-Order Bonuses. A standalone Japanese release is scheduled for October 28, 2026 in the same four-disc, 120-track shape, holding music carried over from the mobile game alongside the 33 pieces written new for this one. Square Enix's music label now carries that release on its own product page: October 28, 2026, at 4,620 yen including tax, as a four-disc set of 120 tracks, with a note that its contents are identical to the CD packed into the Collector's Edition. The published track list does not mark which pieces are new and which are carried over, so a track title on its own says nothing about what appears in this game. The 120-track figure itself is firm, printed in the Collector's Edition contents in both English and Japanese. Outside Japan, Square Enix's North American store lists the album as an imported CD from Japan at $36.99, open for pre-order as of October 23, 2026, with its release date given only as an approximate November 2026.
