Miley Cyrus, 'Wake Up America'
On her second album, 2008's Breakout, Cyrus delivers an impassioned, nakedly Auto-tuned missive of sustainability to the Facebook generation – and, like much of her teen fanbase fixated on Farmville, she hasn't bothered to crack a newspaper about the topic. "Everything I read is global warming, going green/I don't know what all this means," she chirps happily over a handful of power chords. Not the most dynamic contribution to the conversation, but who knows: one more song positioning all the ecological blame Stateside, and maybe we'll finally sign the Kyoto Protocol.
