If we're talking about submitting lossless audio for the blu-rays, I know a new isolated music track was created for Star Wars, but I've already conformed my isomix tracks for Empire and Jedi, if there's interest. For Empire, in addition to the isolated score, I created a third audio track that mixes in the unused music with the '93 laserdisc audio, so there's music throughout almost the entire film. I've also updated the Jedi isolated music track to include the sail barge music. (Ripped from the surround channels of the 2004 DVD.)
