The pop-punk powerhouse quartet don't go completely Green Day on their new fourth album, but they do inch toward something resembling maturity. On refreshingly poignant tunes like ''Guts'' and ''Time-Bomb,'' the sugary choruses sparkle so thoroughly that the yell-about-parents-and-girls moments don't get in the way. Dirty Work proves you can grow up and still act like a kid — just as long as your songs are this head-rushingly catchy. B+
