She's as feisty as Pink, as beat-savvy as M.I.A., does Eurodisco better than Gaga. But can this mercurial diva, a star in her native Sweden, crack the Billboard Top 40?  The second EP in Robyn's Body Talk trilogy (PT 1 was in June) offers up another batch of great, club-ready songs that are a touch too weird for American hit radio. Robyn sings and raps about standard diva themes (dance-floor ecstasy, self-reliance), but the music is deliciously wacked-out. In "U Should Know Better," she boasts alongside Snoop Dogg as a churchy choir swells over fuzzy effects. "We Dance to the Beat" is a thumper that slides from Eighties electro into squiggly abstraction. As far as the radio goes, Robyn has other priorities. "We dance to the beat," she croons, "of silent mutation."
