Finally, my area of expertise!
(And by area of expertise I mean "hey, I downloaded that!")
Taken straight from the NFO distributed with the music:
This is the music from the 4th disc of FFVII International, which contains various infos,
pictures, movies & even more. I haven't been able to identify the composer; maybe it was
still Nobuo Uematsu...? If anyone can confirm a name, please let me know.
Basically it's an omake disc (the official name being something like "Final Fantasy VII Perfect Guide" - ファイナルファンタジーVIIパーフェクトガイド), and some completely original (?) music (although there are some references to classic FF songs) plays on it's various menus . It's likely the only way we'll know who composed it is to find a copy of the credits of the International version. However, I can't think of any reason why someone would feel the need to put those on the internet, and it's possible that even then the creators of the omake disc/the composer of the music isn't credited.
It MIGHT be Uematsu. But somehow, listening to the music, I kind of doubt it. I'll poke around a bit (this kind of futile googling is my biggest hobby)
EDIT: well, one track us definite composed by Uematsu - the last one, which a straight copy of "Opening ~ Bombing Mission" (I think it plays during a movie that shows how the opening movie was made)
