The Smashing Pumpkins latest tour is being held to the heat by critics and fans who say the band is out of touch with their audience. The problem? They aren't playing enough of their hits. When ticket prices are often at a premium, fans are going to the concerts with some expectations. Do musicians have an obligation to play "the hits" at concerts?

Does being obligated to play the hits necessarily compromise artistic autonomy? Are musicians facing a different set of rules than other artists? As a fan, have you ever felt you didn't get your money's worth when the band sticks to its new stuff?
