Sally Kohn: In menswear, if you buy a normal suit off the rack, it has four buttons on the sleeve but they don't actually open. She says that's because people used to unroll their sleeves when they were in their suit to do work and they didn't do that anymore. Kohn: The same thing like recorded music is going to basically render the art of playing music obsolete. "The premium music experience is not listening to music on your stereo or on your phone"
