"American Idiot" Green Day 2004

Before becoming a bloodless Broadway musical, the title track of the '90s pop-punk trio Green Day's comeback album was a proper rallying cry for young people around the world who felt frightened and disenfranchised by the excesses of the Terror Era. Rather decrying the war, or even the president directly, Billie Joe Armstrong pushed back against the post-9/11 government- and media-fuelled hysteria and paranoia that tried to shutter dissent while uniting everyone who didn't want to be "part of the redneck agenda." Plus, unlike Eminem's entry, you could actually mosh to this.
