One thing that’s really bothered me about the ST is how every film in the trilogy ends on the same piece of music, the “Binary Sunset” theme. If/when I get around to editing this trilogy, that will be top of my list to change.
I think it would be poetic to end TROS on the “Throne Room/Finale” music from ANH, probably utilizing the slower/more epic sounding unused second half of the theme, starting at 3:29 here: https://www.youtube.com/watch?v=0Ca5A-7wy_A
