Less than a year after A Year Without Rain, Selena Gomez picks up where that album left off: on the dance floor. Only this time, she's staying out late (and possibly at a 21-and-over club). Sun is a sleek, chic and, yes, sexy affair that starts off planting four firmly on the floor and doesn't let up through sassy kiss-offs, catwalk struts and Gomez's first Spanish track. It's all perfectly crafted. Maybe a little too perfect, painted as it is in shades of La Roux, Ke$ha, even Blondie! At least Gomez's touchstones are good ones. And her sweet purr is stronger than ever.
