I thought the quote about proving the idea wrong, that deeply emotional music can only be made by human's first hand, was funny... especially after listening to the deeply unemotional music that was in the accompanying video.
I watched a movie call "A Late Quartet" recently. I thought it did a good job presenting some ideas about how emotions and music intertwine.
