Amazon.comIn the United Kingdom, New Zealand-born Natasha Bedingfield and brother Daniel Bedingfield have seemingly taken up permanent residence at the top of the pop charts. He's an earnest rocker with a dance music bent. She's an altogether more exciting prospect--a singer-songwriter who refuses to sit still, charging through decadent R&B ("Single"), jittery electro-pop ("I'm A Bomb") and first-class balladry ("I Bruise Easily"), invoking the likes of Beyonce and Gwen Stefani. And, okay, sometimes Nelly Furtado. An all-star production team, including former Robbie Williams collaborator Guy Chambers, makes for a debut that sounds like an instant greatest-hits set--just add cheekbones. --Aidin Vaziri
