I fully agree with the OP. Uematsu hasn't provided the same quality of work we can see in FFXI. Pretty music doesn't mean fitting music. I play with the BGM completely off, as i prefer the game's SFX sounds to its boring tracks.

Unfortunately, OP, it's already pretty unexpected Uematsu went out of his way to actually make music for this game. Expecting him to redo it is unrealistic, even though Uematsu himself expressed the desire to change many of the game's tracks, as he was forced to compose them without even seeing the game once.
