The OT music will always be a classic, but I feel it is aging somewhat, especially ANH. I can hardly listen to most of ANH anymore except for the main theme, the Death Star battle, and Leia's theme.

Personally, I disagree with this sentiment completely. Star Wars is my favorite soundtrack of the six. I feel that it works flawlessly on two levels: both as music in itself, and insofar as it develops and exegetes the emotional mood of the film. As much as I enjoy the prequel soundtracks, I'd rather listen to the Star Wars score any day.
