2.“Numb” by Linking Park for the duel between Anakin, Obi-Wan and Dooku in ROTS
I feel like it would make more sense over the Mustafar duel.
4.“Bohemian Rhapsody” by Queen for Luke facing down the FO walkers
I can definitely picture music exploding at “momma, ooh-ooh-ooh” at the exact moment all the walkers fire on Luke.
