Which Earth songs should aliens listen to?

The question posed by this uncharacteristically interesting Livejournaler is a damn good one: What should Earth upload into extraterrestrial iTunes folders? What song could represent the scope of human history to beings utterly beyond our cultural understandings? Perhaps a Muddy Waters tune to showcase our knack for turning suffering into respected art. Or something by the Sex Pistols to represent how even four drunken idiots who hate each other can change the world and inspire others to do the same.
