The music of the video game Final Fantasy IX was composed by regular series composer Nobuo Uematsu. It was his last exclusive Final Fantasy score. The Final Fantasy IX Original Soundtrack, a compilation of all music in the game, was originally released on four Compact Discs by DigiCube in 2000, and was re-released by Square Enix in 2004. A Best Of and arranged soundtrack album of musical tracks from the game entitled Final Fantasy IX: Uematsu's Best Selection was released in 2000 by Tokyopop Soundtrax. Final Fantasy IX Original Soundtrack PLUS, an album of music from the game's full motion videos and extra tracks, was released by DigiCube in 2000 and re-released in 2004, and a collection of piano arrangements of pieces from the original soundtrack arranged by Shirō Hamaguchi and performed by Louis Leerink was released as Piano Collections Final Fantasy IX in 2001.
The game's soundtrack is best known for "Melodies of Life," the theme song of the game, performed by Emiko Shiratori in Japanese and English. The song was released as a single by King Records in 2000. The soundtrack was based around a theme of medieval music, and was heavily inspired by previous Final Fantasy games, incorporating themes and motifs from earlier soundtracks. The music was overall well received; reviewers found the soundtrack to be both well done and enjoyable, though opinions were mixed as to the reliance on music of previous games. Several tracks, especially "Melodies of Life", "Roses of May", "Vamo' Alla Flamenco" and "Not Alone" remain popular today, and have been performed numerous times in orchestral concert series, as well as being published in arranged and compilation albums by Square as well as outside groups.
