I mentioned it already in the general thread, but besides obvious suggestions like Duel of the Fates or Across the stars, I have a less-known prequel theme in mind, one that is prominent in the second half of ROTS. It’s a Sith motif named “Mystery of the Sith” also known as the second half of Padmé’s Ruminations. It has early hints to the “Anthem of Evil” theme if you listen it closely.

TROS really should serve as a culmination of the saga in all its aspects, including the score.
