I actually loved that "The Arena" finally got screen time in ROTS. While I hate 99% of Ben Burtt's musical decisions, he did two things in ROTS that I really did like:
1) The "War Drum" opening to the film.
2) "The Arena" when Vader and the Clonetroopers march on the Jedi Temple. The first moment I heard that cue during the midnight showing I thought (as I do now) THAT moment was worth saving the cue for. Too bad he had to butcher the end of it. I'd have liked the full cue to be played over an extended attack sequence in the temple.

Otherwise, yes, he recycled WAY too much music in the last two films. Everything on Geonosis is utterly unforgivable. Conveyor belt? The actual Attack of the Clones? Ugh!
