Natasha Bedingfield

Hottest Song: "Pocketful of Sunshine"

The song that's really gone on forever? Natasha Bedingfield's "Pocketful of Sunshine." The single was released in February, and it's still going strong on the charts! But c'mon -- it really is the perfect summer song. Keep this track at the ready on your iPod, and as soon as the winter doldrums start to creep in, you'll be able to fight 'em off with one little bit of "Sunshine."
