The first time, I really rushed through the process. I had never edited music before and kind of played with it while working.
Originally, I tried to fit a six suites on one disc. By the time I was halfway through with AOTC, I knew it wasn't possible. So the suites got longer and longer. As a result, TPM was extremely short. Plus, I just used MP3 versions as source files.
I went back and expanded the first three suites using wav source files wher ever I could. I also used some unreleased music in all three, most of all in ROTS.
In addition, version one played seamlessly from beginning to end. With v2, each suite has a clean ending and beginning. I made an effort to have each suite stand on its own.
Basically, the prequel trilogy went from 71 edits to 58 edits used in TPMv2, 46 edits in AOTCv2, and a whopping 81 edits in ROTSv2. In addition, the prequel trilogy used to run 56:35. Now it runs 77:05; 20:30 longer.
Not only is this work expanded, but it feels a bit more cohesive, too. I think its a better listening experience.
