I love the Giza Plains track.
The reason that Uematsu's music was so perfect for past games was that the animation and total lack of voice acting meant that much of the story had to be told through the music. Now, we hear the characters and can see everything better than ever before, so the music can take a backseat and let the visuals and voices speak for themselves. Not that the music's bad, it's just incredibly subtle. Like listening to Mendelssohn or Brahms as opposed to Mozart. Mozart will blow you out of your seat with beauty, but Mendelssohn will kidnap you and take you to another world before you even know it. Uematsu's music is profound and as a listener you have to hear it from the outside to enjoy it, but Sakimoto's music you can enjoy from within.
again, love the giza plains, although the entire set is making me happy so far.
