"Music: As the movie progressed, the music became infinitely better. It was downright beautiful towards the end. But…I can pick out tracked cues very very easily, and there were quite a few in this movie. Tracked from TPM, tracked from AOTC- and I could even tell what scenes they were from as I listened."

Agreed absolutely. Most aspects of ROTS improved as time went on, and the music certainly helped.

As to AOTC, I was under the impression that Williams didn't want an isolated score, because so much of it was tracked from TPM.
