A little knowledge is a dangerous thing; it's hard not to fit new information/experiences into existing contexts that you're familiar with. For example, every time I read something about the economy I fit it into one of the macro frameworks I've learned at work. Which is useful and relevant, but I think it can blind you to the nuances of any particular situation, especially with a topic as complex as the economy.
I bring this up because I'm starting to see a similar dynamic happening with my relationship to music, ever since I really started studying theory and composition. It's one thing to listen to a piece and think, "this part gives me tingles. I like that." It's another to say, "I really like the use of the Lydian dominant and how it modulates to Dorian minor a major third above." I'm starting to move from the former to the latter.
What irks me slightly is that I think there's an element of music appreciation that hinges upon not understanding the theory behind it. People like music for all kinds of reasons: lyrics, timbre, mood. Being able to hear chord changes on the fly gives you a structure you can use to interpret what you hear but creates an extra element of predictability that I think can blunt an aspect of the aesthetic experience. I guess it's a little like magic: once you know how things are done it's less exciting..
