I just programmed all the music of the entire 6 episodes in order on my computer and play that. I have the official ROTS soundtrack in my car for when I feel like that. I think it is my favorite score of all the films at the moment. I rarely have time to listen to my entire larger compilation. I think it takes 8 hours or so to play through (and I'm missing the new John Williams Ewok Celebration score from ROTJ:SE) I usually start the larger compilation from whichever point in the Saga I feel like listening from - usually ROTS as well, sometimes AOTC if I want to start off with something sort of quieter.
