Nobuo Uematsu, the main composer for the regular Final Fantasy series, contributed one track to the Ring of Fates soundtrack.

Final Fantasy Crystal Chronicles: Ring of Fates Original Soundtrack and the double A-side "Hoshi no Nai Sekai"/"Yokogao" were released by Pony Canyon in 2007.

The latest release is that of Final Fantasy Crystal Chronicles: Echoes of Time Original Soundtrack by Square Enix in 2009.

"Morning Sky", the opening theme for Crystal Chronicles, was played in the first Games in Concert performance in Utrecht, Netherlands on November 26, 2006.

Kumi Tanioka has described the musical style for the soundtrack to Final Fantasy Crystal Chronicles as being based on "ancient instruments".

[2] She also credits Hidenori Iwasaki, the synthesizer operator for the game, with doing "fantastic technical work" that brought her vision to life.

She said in regards to the soundtrack that "instead of the traditional sound endemic to the specific areas, I wanted to use them as one flavor and blend many colors just like Final Fantasy Crystal Chronicles" and that many of the tracks she created would be "actually impossible to perform" in real life.

The album did not include the English versions of the opening song, "Sound of the Wind" and the ending theme, "Moonless Starry Night", all sung by Donna Burke.

He enjoyed the alternative instruments used in the tunes, calling them "successful in providing imagery of renaissance times", although he felt that much more of them would have begun to drag the soundtrack down.

Jared felt that it was "a decent look into the soundtrack of Crystal Chronicles", but not as good of a sampler disc as it could have been due to the track selection.

The ending theme song for the game, "A World Without Stars" (星のない世界, Hoshi no Nai Sekai), was sung by Aiko, though it was not included in the album, and Nobuo Uematsu contributed one track to the soundtrack.

He disapproved of the change from the medieval instrumentation to a more orchestral score, and felt that the pieces had much less emotional intensity than the Crystal Chronicles soundtrack.

Like previous Crystal Chronicles soundtracks, Echoes incorporates a variety of instruments, including oboes, xylophones, marimbas and Latin guitars.

[13] "Sound of the Wind" (カゼノネ, Kaze no Ne) is the opening song of Final Fantasy Crystal Chronicles, composed by Kumi Tanioka and performed by Yae.

While "Kaze No Ne" follows the medieval theme of the rest of the Crystal Chronicles soundtrack, the arranged version is a more "produced" techno-sounding track.

[15] "Hoshi no Nai Sekai"/"Yokogao" is double A-side containing the theme song to Final Fantasy Crystal Chronicles: Ring of Fates "A World Without Stars" (星のない世界, Hoshi no Nai Sekai), as well as two original tracks, "Profile" (横顔, Yokogao) and "Love" (恋愛, Renai), and instrumental versions of "A World Without Stars" and "Profile".

He felt that "A World Without Stars" was a "terrific piece, and that the other two songs, while "not as strong", were "still decent tracks that were easy on the ears", and approved of the instrumental versions included in the single.
