Three ways of describing today's show:
1. A Mashup Of Planet Money and American Top 40.
2. An econ summer mixtape.
3. How the top three songs in America explain the crazy transformation in the music business.
(Those three songs by the way, are by Macklemore & Ryan Lewis, Justin Timberlake and Icona Pop. They come from last week's America's Top 40.)
