Attention Ke$ha fans who thought they were enjoying monster radio hits like “Tik Tok” and “Your Love Is My Drug” ironically: The paragon of bag-lady stylishness is in on the comically exaggerated awfulness of her disreputable (and maddeningly catchy) 2010 debut Animal, and she isn’t afraid to push herself into full-blown ridiculousness on the new “mini-album” Cannibal. The ghoulish title track has the notorious man-eater literally feasting on human flesh, expressing ambivalence for a former crush (“Now that I’m famous, you’re up my anus”) while likening herself to Jeffrey Dahmer as she licks up the guy’s liver and uses his finger as a teaspoon. The way Ke$ha openly, even gleefully courts gross-out obnoxiousness doesn’t totally justify her music’s inherent evanescence, but damn if Cannibal isn’t just as giggle-inducing as Animal.
