Eh, I’ve seen the Battle of the Heroes and DotF music mentioned multiple times here, but personally don’t know why we’d want to borrow a prequel-specific theme for the final Kylo/Rey duel. To me, this screams TPM and ROTS. It’s not like the main SW theme, or Force theme, etc. that’s been used across the whole saga. These are very specific to certain people and/or events and don’t come across as a good fit to me for this fight. For the hell of it, here’s a different take I just made that mixes in some Kylo and Rey motifs. See if you guys recognize the source. Seems like a better fit to me for the first half of the battle before JW’s The Final Duel music kicks in.
