Fair enough. I may be snobbish, I may be arrogant and I may be an idiot, but you have to remember that everything I say is just my opinion. I am not forcing anyone to believe me. You can have your own ideas on what is good and what is bad and I can have mine.
I like Schumann because of the personal, intimate, and emotional nature of his music.
I don't like frogslegs because he's snobbish, arrogant, and an idiot.
I like Bach because of his innovative weaving of harmony with counterpoint. He uses counterpoint in such a way that the harmony is illuminated from it, and vice versa.
I don't like Mozart because I find his melodies (with their accompanying harmony) to be overly simple and repeated far too often. I also find his harmonic foundation to be rather limited compared to someone like Beethoven or (going backwards) Bach.
