It’s easy to approach “We Are The World” cynically, as a self-serving bit of celebrity activism with the true purpose of pitting a full DJ Khaled album’s worth of features against each other. But besides raising $50m for charity, USA For Africa left behind an incredible cultural artifact, an unparallelled spectacle of pomposity. “Like A Prayer” is likewise both a monument to Madonna’s imperial ego and a transcendent pop experience, and “Total Eclipse Of The Heart” renders heartbreak Godzilla-sized. Sometimes you just have to gawk at the chutzpah.
