Jack Black and his Tenacious D bandmate Kyle Gass join Keegan-Michael Key to learn how music affects the brain. Games and demonstrations include a round of musical mad libs, "Odd-itory" illusions and experiments that show how music can affect our perception of images, emotions and even taste. Master mentalist Lior Suchard asks Black to think of any song in the world and tries to guess it correctly.
