I can't say for sure that I learned more on my own than from school, but certainly I learnt a ton of knowledge that should be taught in school. I'm glad I got such a positive response, I was afraid that I'm going to get beaten to death with sticks for that "pop culture pulp". I can already imagine it "You're so closed minded, Miley Cyrus is liek tha most talented artist evur".
I don't really fancy Bach that much, but I have a great appreciation for his legendary work. You said that you think there is a lot of emotion in his work, I think quite the opposite. His works are very organized, mathematical. In fact, I don't think there is any composer in the history that we know of, that ever even came close to the genius of Bach in his structure of the composition. My favorite piece composed by Bach is the same you linked in your post, Toccata and Fugue.
