Yes, la Brit is back with a first official taste from her still-untitled seventh studio album, due in March. Would you hold it against her, though, if the song’s chorus cribbed pickup lines that went out with mood rings and Midori sours? ”If I said I want your body now/Would you hold it against me?/’Cause you feel like paradise/And I need a vacation tonight,” Spears coos mechanically over frantic synths and a shuddering, strobe-lit breakdown that belongs on a far more interesting song. Even with studio Svengalis Max Martin and Dr. Luke on board, ”Hold It Against Me” brings only mild fire to the dance floor — not exactly the scorcher 2011 was waiting for. B
