The Official Katy Perry Divorce Anthem is a predictably effective piece of angsty dance-pop - it was co-produced by Dr. Luke and Max Martin, after all. It's also just plain predictable. The minor chords signal "dark, serious"; the lyrics supply tabloid bait ("You can keep the diamond ring/It don't mean nothing, anyway"). But Perry is best at fluffier stuff; she lacks the gravitas, and the lung-power, to drive the song home. Russell Brand: you can rest easy, mate.

“Baby Got Back”

While watching a Budweiser commercial during the Super Bowl, Sir Mix-a-Lot thought the skinny female models in the ad didn’t represent reality. So he wrote this ode to ample bottoms, featuring its famous to-the-point lyric: “I like big butts and I cannot lie.” MTV banished the video, featuring shaking booties and sexually suggestive fruit, to 9 p.m. or later. “I thought my career was over,” he told Rolling Stone. “Then I called Rick Rubin, and I told him the video was banned, and he was like, 'Great!' We sold another 2 million records.”
