Well, in my book, discussions about superlatives in music are futile. It's like arguing whether the ocean is more beautiful than the mountains - both have vast amounts of perfect and incomparable beauty. I think the same goes for music. Almost every genre of music has a number pieces that are at the pinnacle, that could be considered "incomparable."

In every genre you listed, I can think of pieces that I enjoy listening to, over and over again. In certain genres, there are pieces I enjoy performing, over and over again - never being able to exhaust the nuances of the beauty of the piece.

I think your last paragraph indicates you believe the same thing. In light of that, would you care to rephrase your question, so I can retitle the thread to something that doesn't become another futile argument about which incomparable piece is most incomparable?

How about "Musical Pinnacles"?
