Hmm - I agree with your comments there about the music in the LS battle: all the saber battles in the 6 films are mostly without music for the very reasons you stated. Adding the soundtrack makes it feel less intense - in my opinion.

However, the TIE shot you are talking about seems to be the one 'holy shite that's brilliant' shot that most people have picked out as excellent, so I cant understand where you are coming from there. The cloned TIE shot Ady posted a while back looked precisely that - cloned, and therfore utterly fake. The big TIE reveal combined with the Imperial March is a standout moment of the whole edit I reckon.
