While I'm playing music on my MP3 player, it is almost always set to shuffle. I believe in variety and unexpected combinations, and radio stations have not provided that at any time in my memory. When you hear "your station for variety" or other taglines, it never refers to a combination of rock, country, jazz, classical, spoken word, and other genre. Why not? A format with that challenging combination might never lead the market, but a program like that might prove to be the second choice for a very large set of listeners.
