I disagree with the overall sentiment here. I absolutley love the music from the PT, especially the emotional tone it was trying to reach. I thought it suceeded with that and didn't overdramatize anything. I also didn't mind the "tracked" music that was used in Sith. I assume by "tracked", you mean previously used themes from the OT? If so, then I thought it was appropiate and I would've been disappointed by not hearing some of the previous themes.
All of that said, though, I do still prefer the OT scores.
