I think it would be easier to give my opinion by part.

part one doesnt do so well for me, especially the music during her singing...

part two syncs well at the start but the part with tornado does not seem like a slow song scene to me...

part three goes perfectly well with it, I can see where people would think something here...

part 4, again not so well except that the minchkins dance with the beat.

part 5, the beginning is ok, once again all the dancing is to the beat, but the part with the which doesnt go well, and then at the end it does go pretty well

part 6..people are praising it but I really dont see it, the music doesnt change in tempo that much and it hardly fits the scarecrow's personality at all, which is what the scene is suppose to be focused on.

part 7, only parts that sync are the scarecrow standing up and the tin man getting oiled...

all in all, Im not too impressed except with part 3. All the rest the music simply rises and falls as it should, but it was enjoyable none the less
