Masahiro Sakurai, the director of the Super Smash Bros. series, confirmed through his Twitter account that two Final Fantasy VII remixes featured in Super Smash Bros. Ultimate will be available with the Digital Deluxe Edition of Theatrhythm Final Bar Line. These songs are “Cosmo Canyon” and “Aerith’s Theme.” They are distinguished from the original FFVII songs under the “collabo arrange” title.

The Digital Deluxe Edition of Theatrhythm Final Bar Line includes 27 new tracks, some of which are arrangements of classic songs in different genres. Square Enix already released a list of all the songs included in the Digital Deluxe Edition, as well as the new songs included in the first Season Pass. Some of the songs included in the first Season Pass are from the SaGa series, Live-A-Live, The World Ends With You, and the NieR series.
Nintendo and Square Enix have been doing music collaborations for a while now, as the Sora DLC for Super Smash Bros. Ultimate included a promotional tie-in with another Square Enix game. People can unlock the music track “Dearly Beloved -Swing Version-” for use in SSBU, as long as their Nintendo Switch console has save date from Kingdom Hearts: Melody of Memory.
Theatrhythm Final Bar Line will release for the PS4 and Nintendo Switch on February 16, 2023. You can check out Siliconera’s review of the game here.
