The theme song used for the PlayStation 2 version is, once again, sung by
then up-and-coming JPop group, day after tomorrow.
 The new theme song entitled "Soshite Boku ni Dekiru koto" gives the listener
a sort of view of the world of "Symphonia" much similar to the game's first theme
song.

 The song is penned, and co-arranged by the group's sound producer, Mitsuru
Igarashi, a former member of the popular JPop group, Every Little Thing, known
affectionately as ELT to fans. The track, like Starry Heavens, is composed
by the group's keyboardist, Daisuke Suzuki.
 The song is included in the group's ninth single entitled, "lost angel," and serves
as the second track.
