Colbie Caillat's smash 2007 debut single, "Bubbly," established her as, well, bubbly — a slightly ditzy Southern California gal specializing in folk-pop ballads about getting "the tingles in a silly place" when she sees a cute boy. On her second CD, she's still crushing on guys. "I think I felt my heart skip a beat/I'm standing here, and I can hardly breathe," she coos in "You Got Me." Caillat has a fine voice — clear and ringing, with a hint of a rasp — and she can write hooks. (She co-composed every song here.) But the simpering puppy love grows wearying over 12 tracks, especially because Caillat fails to convince as a romantic heroine. She sounds too goofy — too bubbly and tingly — to be lovelorn.
