Colbie Caillat is just so, well, bubbly. Taking a career cue from her breakthrough 2007 hit, the California girl comes by her sunny pop naturally. Her dad co-produced Fleetwood Mac's Rumours, quite possibly the quintessential L.A. pop album. But Caillat leaves all the relationship baggage and lines of coke behind, opting instead for breezy acoustic guitar runs, cooing vocals, and enough perky melodies to fuel a Hello Kitty fan convention. Her third album, All of You, is packed with good vibrations: "I Do," "Brighter Than the Sun," "Think Good Thoughts." There's not much depth to Caillat's songs — "I want to be your favorite song" she sings on "Favorite Song," and "I Do" pretty much comes down to the title repeated three dozen times — but summer's not the time for thinking. Pour a cool one and dive in. —Michael Gallucci
