I loved the music change myself, and it worked tremendously with the editing, cutting back and forth to the escapees at just the right times. Sounds so dramatic when Han goes "let's hope he got that tractor beam out of commission" and it cuts back to the duel.
However, what ChainsawAsh said above is certainly interesting. There are musical cues in the other OT duels, but only at dramatic moments, whereas the ANH:R duel as it stands now has constant music.
So basically I'm on the fence.
