This upstart U.K. girl group doesn’t get too weird on their third outing, but they do set aside attempts at mining stateside R&B in favor of fat pop gloss. And the switch suits them fine, whether dropping sha-la-la’s like Ronnie Spector (“Love Me Like You”) or tossing out the year’s finest electro-disco chorus (“Black Magic”). And you want funny? Check out “Weird People” (best slo-mo vocal hook since Yello’s “Oh Yeah”) or the I’m-gonna-wash-that-dude-right-outta-my-life rallying cry, “I call my girl ‘cause I got a problem, only a curl is gonna solve it,” on “Hair.”
