The music of the video game Final Fantasy X-2 was composed by Noriko Matsueda and Takahito Eguchi. Regular series composer Nobuo Uematsu did not contribute any of the music, despite having composed around half of the soundtrack for the first game, Final Fantasy X. The Final Fantasy X-2 Original Soundtrack was released on two Compact Discs in 2003 by Avex. After the release of Final Fantasy X-2 International + Last Mission, an album entitled Final Fantasy X-2 International + Last Mission Original Soundtrack composed of the songs added to the soundtrack for that game was released in 2003 by Avex. Final Fantasy X-2 Piano Collection, a collection of piano arrangements of the original soundtracks by Noriko Matsueda, Takahito Eguchi, Hiroko Kokubu, Masahiro Sayama, and Febian Reza Pane, was released by Avex in 2004.
A single by Koda Kumi entitled real Emotion/1000 no Kotoba, based on the theme song for the game and the ending credits song, was published by Rhythm Zone prior to the game's release in 2003. Another single, titled Kuon: Memories of Waves and Light – Music from Final Fantasy X-2, was released by Avex in 2003 along with the original soundtrack. It consisted of live arrangements of several of the game's songs, composed and arranged by Noriko Matsueda and Takahito Eguchi. A set of three singles entitled Final Fantasy X-2 Vocal Collection- Paine, Rikku, and Yuna was published by Avex in 2003, with each single including vocal arrangements of songs from the game, sung by the respective character's voice actress.
The soundtrack received mixed reviews from critics; while several felt that the music was good and keeping in tone with the game, others found it to be odd and shallow. Several reviewers attributed the change to the lack of participation by Uematsu. Final Fantasy X-2 International + Last Mission Original Soundtrack and Final Fantasy X-2 Piano Collection, on the other hand, were very well received by critics, who felt that they were far superior to the original soundtrack. The singles for the soundtrack were poorly received by critics, who found a few of the songs to be enjoyable but all of the singles to be overpriced.
