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.

“V.T.T.L.O.T.F.D.G.F.”

Quite a few musicians have utilized initials for song titles -- Michael Jackson's "P.Y.T.," Abba's "S.O.S.," Donald Fagen's "I.G.Y.," etc. But the more curiously initialed tune has to be "V.T.T.L.O.T.F.D.G.F.," short for "Voyage to the Land of the Freeze-Dried Godzilla Farts." Fishbone's original guitarist, Kendall Jones, explained to Rolling Stone, "When Norwood [Fisher] wrote it, he introduced it to the band saying, 'Man, I've been hearing about all these Nazi right-wing groups on the news saying the Holocaust was staged. So what if America said it never dropped two atom bombs on Japan, that it was actually Godzilla popping a couple off?' Only Norwood would come up with something that out." The same year "V.T.T.L.O.T.F.D.G.F." was released, the film Godzilla 1985 appeared in North America.
