Let's translate the black square to the world of music: Press the C key on your piano and hold it down for a full minute then release. This is the "music" released by someone who later became renowned for this music. The music experts call it an amazing work of art. You disagree, and you're told to take a music history class if you want to understand why that one-note music is an amazing work of art. Ridiculous, isn't it?

To me your black square is a 1-minute C note, and your soup can is "Mary had a little lamb".
