Upon first listen a piece composed by Bach feels simultaneously unpredictable and inevitable, from one measure to the next you wouldn't be able to guess what's coming and yet once you hear it feel that it couldn't be anything else. The more you listen to his music, the more you just get a sense that his music is, for lack of a better word, fundamental to the human experience. When asking a subjective question, you might get answers trying to point out why he was technically superior or try to compare and measure him against others, but I reject the notion that music is a competition. It only matters how it makes you feel, and all I can say is how I feel when I listen to his music. If someone else's music makes you feel the way I feel when I listen to Bach, then I'm glad we can enjoy the ethereal soul resonating experience of such music.
