It's kind of an unfair comparison..but I guess that would happen given the circumstances.

Nobuo had some 82 tracks written before the Alpha version of 1.0 was even out (as evident by the music files released from that version). He had to go off concept art and pretty much everything was hush-hush.

Soken on the other hand, has had intimate knowledge of the lore and the ideas behind many things, and has been privy to the info of 2.0 since its decision to relaunch.

So to say that Uematsu was "uninspired", is not really accurate. He worked with what he had. Does the music sound unconnected in some places? Definitely. But I blame that more on Tanaka (lolz) than Uematsu's writing skill. Uematsu DID compose "Answers", since he had working lyrics and an idea of what it meant. Of course, the song is successful
