Goodbye, Hank and Patsy. Hello, SHeDAISY and Britney. Nineteen-year-old country star LeAnn Rimes’ first cowriting venture (with Andres Carlsson and hit-meister Desmond Child) finds her catering to her fellow teenyboppers with bouncy dance-pop, rather than to her mom ‘n’ dad’s boot-scootin’ pals. Thanks to the catchy chorus (with its U2-esque guitar lick) and bitter but positive lyrics — not to mention Rimes’ to-die-for vocals — ”Life Goes On” will probably go on to No. 1. On the pop chart, natch.
