What is your favorite clical music song and composer? (aficionados only)?

My favorite composer is a tie between Mozart, Beethoven, and Chopin. Chopin has great romantic songs, Beethoven has such booming greatness, and Mozart has simple, quick, and lively songs that are quite fun to play. My favorite clical song is Waltz #10 in B minor. Such a lively, fun, yet serious and respective song to play.
