I knew that would get a rise out of you. It is merely my preference. Undoubtedly, it has something to do with having listened to it so many times. To make an even more dreadful confession, I didn't even like ANH when I first saw it. Only ESB drew my interest into the larger story.
"Perhaps because ANH was written to sound like Classical Music?"
Obviously it draws heavily from classical music, which is why I like it. However, it has influences that were modern at the time, which haven't aged so well.
