I was kindly given a superb expanded version of Episode II sountrack by a forumer, which will keep occupied for one or two months.
I now only lack Episode III. If someone knows somebody who has compiled an expanded soundtrack for episode III, I would be very happy to get the information.
A guy mixed a few unreleased queues from several sources but some of them still have sound effects in them, here’s his playlist: https://www.youtube.com/watch?v=2nYxLzlt4vQ&list=PL0dqWRYwKNGdnCpOqJsKcSWc5nJYgbY3A
