Here's an idea that may or may not be worth pondering, but I'm curious for your opinions

If through some freak, unimaginable (except for now

) occurrence, all the music of all classical composers was destroyed, except for that of one composer--- which composer's works would you preserve and why?
This is different from asking "Who is your favorite composer?" because for me, I'd be torn between Rachmaninov, Beethoven, and Bach for personal preference, but would certainly preserve Bach's works for their huge value in the development of counterpoint and musical quality.
any thoughts??
