2. Pink's So What
Click center arrow to play
Justin Timberlake's "Cry Me a River" remains the greatest rebound song of all time, but at least Pink can say she made a spirited run at the crown. "So What" packs in chanting, hand claps, a nursery rhyme melody and a chorus overdubbed until it sounds like 50 Pinks are calling her ex "a tool." It's the least subtle act of pop vengeance since Lisa "Left Eye" Lopes lit a match. It's also astonishingly fun thanks to the rubber-ball bounce of producer Max Martin's keyboard hooks and Pink's swaggering, emotional vocal. You definitely don't want to break up with her, but no song this year was as much fun to go out with.
