The cute-as-a-button teen pop duo M2M could be filed away easily in the Spice Girls/Britney Spears cubbyhole, except there's no big producer behind these Norwegian divas pulling the strings. There's no one plucking strings for them on their Atlantic Records debut, either — these fresh-faced 16-year-olds write peppy sunshine nuggets and color them with their own delicate, jangly fretwork and shimmering keyboards.
