For TPM we practically have everything, minus the film version for "Augie's Great Municipal Band". All though for my edit I did a hybrid of rear channel DVD rips and clean music for that cue. I did include the clean album version as a bonus track.
For AOTC I would say we have maybe 50% of the score clean. For ROTS we have probably about 98% of it clean.
These were posted in a different part of the forum, but you may not have access to it. Anyways here are my complete intended edits of the scores. AOTC and ROTS do have rear channel DVD rips for the non clean music. There are also synth mock-ups in my AOTC and ROTS edits for pieces that have never surfaced. I know someone who has the sheet music for both of the scores and he used that to create the synth mock-ups. He can't trade the sheet music, so don't ask.
Anyways I'll post the links below, just be sure to use gapless playback since cues run into each other like they do in the film. Keep in mind these were edited to be the intended editions. They're not film version edits like a lot of people seem to do.
