Final Fantasy XIII-2 is a role-playing video game developed and published by Square Enix in 2011 as the sequel to Final Fantasy XIII. The music of the game was composed by Masashi Hamauzu, Naoshi Mizuta, and Mitsuto Suzuki. It was intended to sound different from the music of previous Final Fantasy titles, featuring more musical styles and vocal pieces. Since the release of the game, Square Enix has published the 2011 four-disc soundtrack album, Final Fantasy XIII-2 Original Soundtrack, as well as an album of arrangements and alternate versions of tracks from the game, Final Fantasy XIII Original Soundtrack PLUS, in 2012. The theme song for the game, "Yakusoku no Basho" (約束の場所, The Promised Place), was released by singer Mai Fukui as a single in 2011, and the English version of the song, sung by Charice Pempengco and included in the non-Japanese versions of the game, was included on her 2012 album Infinity.
Reviews of the soundtrack album were positive, with critics praising both the variety of styles and quality of the pieces. Several critics noted Mizuta's work as possibly his finest to date. Reviewers of the game were more mixed, with some feeling that some of the styles of music did not match where they were played in the game. Critics were also mixed in their opinions of the arranged album, feeling that several of the pieces were simply inferior versions of the original tracks. Both of the albums and the single sold well enough to place on the Japanese Oricon charts, with the original soundtrack album reaching a peak of #13 and remaining on the charts for eight weeks.
