0:12-0:25 low male voices as we see Snoke. We hear this low male chorus twice at this point in the movie: First at the 93-minute mark, second at 98. On this track of the soundtrack, we only hear it once. Which one (or is it both) comes from the soundtrack? I don't know.
Interestingly, immediately after the second instance of those low voices (at 98 minutes into the film) Palpatine's Sith Theme is heard in the movie. That is absent from the soundtrack, so I suspect editors borrowed this music from Return of the Jedi. Consequently, I do not believe John Williams ever intended Palpatine's Sith Theme to be used in reference to Snoke.
1:17-1:33 Force theme, B-flat minor, 1st and 3rd phrases (but not 2nd), brass, loudly, as Ben kills Snoke. I believe this iteration of the Force Theme was removed from the scene where Snoke dies (about 1:45 into the film - which is where the rest of this track is heard in the film) and is instead used in the scene where Yoda burns down the tree on Ahch-To (about 1:22 into the film – most of which is heard on track 13).
1:33-2:26 incidental battle music, Reylo vs. Red Guards
2:26-2:35 Rey's melody with trumpet and trombone accents, 1st and 2nd phrases, horn, loudly
2:35-3:11 incidental. Kinda sounds like “Rite of Spring” in spots. Reylo defeats guards.
