In an interview with the game's music supervisor Keiji Kawamori published on the PlayStation.Blog on September 14, 2023, he was asked what he could reveal about the soundtrack and music for the game. He responded that because the game's world is much larger than Final Fantasy VII Remake, the team made a variety of new music to go alongside it and also expanded the variety of musical genres used, so he thought there would be a lot to enjoy. They also made many re-arrangements of classic tracks from the original Final Fantasy VII, and Kawamori hoped fans would enjoy comparing both iterations of the same song to see what's the difference. He cited the Release Date Announcement trailer's music being a re-arrangement of the Final Fantasy VII main theme as a battle music track as an example of this to give players a taste of the direction the team chose to take in Final Fantasy VII Rebirth.
