Thanks for the positive comments!
Yeah it addresses the reused Battle Droid music, and the blatant "THEY'RE EVIL" imperial march whilst keeping some kind of continuity.
The track is from the soundtrack of KOTOR2 and is really the only one that seems to fit the movie and feel sufficiently OT.
I don't know about adding any into the battle. There's not much to work with. Between those two clips, I've pretty much used up the whole track - it is videogame music afterall.
If I find a place where it'll work, I'll give it a shot.
