Less than a year after Occupy set up camp in New York City's Zuccotti Park, the movement can boast an official soundtrack. The multi-disc Occupy This Album is a sprawling assemblage of crusty hippies and indie hipsters, total unknowns and American icons, veteran punks and reggae legends. A real-deal highlight is Crosby and Nash's a cappella version of lost hippie gem "What Are Their Names." The oddest nugget is a version of Bob Dylan's "The Times They Are a-Changin'" sung by none other than Michael Moore. He doesn't possess a particularly enjoyable voice. But hey, it's about the message, no?
