What does it even mean for a piece of music to be so long that no person could possibly listen to it? And supposedly you can download the entire piece and it’s only a few hundred kilobytes in size? Shouldn’t it take more atoms than exist in the universe to store a piece of music so large? Or is compression that effective?
