Long before Beyoncé came up with Sasha Fierce, Miley Cyrus was splitting albums with her Disney alter ego Hannah Montana. The duality continues on this soundtrack to the big-screen version of the TV series (in theaters April 10). Seven songs are credited to Hannah, five to Miley. But don't bother trying to tell the difference—just give yourself over to the giddy delights that both have to offer. In addition to its tween-friendly pop-rock, the disc boasts some country courtesy of movie costars Billy Ray Cyrus, Rascal Flatts and Taylor Swift, who delivers the best song, her waltzy new ballad "Crazier."
