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.

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.

However, Uematsu spent an estimated year composing and producing "around 160" pieces for Final Fantasy IX, with 140 appearing in the game.

He felt the theme was medieval music, and was given a two-week break to travel in Europe for inspiration, such as looking at old castles in Germany and other locations.

[1][2] Uematsu has claimed several times that Final Fantasy IX is his favorite work, as well as the one he is most proud of.

[3][4] He also stated in the liner notes for the Final Fantasy IX: Original Soundtrack album that he was "glad that [he] was able to join this project".

[6] Other reviewers such as Engelhorn and Tyler Schulley of "Final Fantasy Symphony", enjoyed the fact that it pulled from previous soundtracks, feeling that it gave the album "the classic feel of the older Final Fantasies" while still being "original and beautiful".

It was arranged by Nobuo Uematsu, Shirō Hamaguchi, Kunihiko Kurosawa, and Haruo Kondo.

Emiko Shiratori supplied the vocals for "The Song of Zidane and Dagger" and "Melodies of Life (Silent Mix)".

[15] It was very well received, with reviewers finding the tunes to have "great dynamics" and "incredibly well made", and that the "orchestrations work wonders with Uematsu's incidental music".

[22] It was performed by Emiko Shiratori in both the Japanese and English versions, arranged by Shirō Hamaguchi, and composed, like the rest of the game, by Nobuo Uematsu.

[26] Additionally, Uematsu continues to perform certain pieces in his Dear Friends: Music from Final Fantasy concert series.

[31] "Vamo' Alla Flamenco" was played at the Fantasy Comes Alive concert in Singapore on April 30, 2010.
