BREAKOUT - MILEY CYRUS

Naming a new album “Breakout” when you’ve already sold 7 million career units seems like a delayed reaction. But for Miley Cyrus, the game plan was apparently “first tweens, then the world.” While it’s still age-appropriate for minors, “Breakout” is for the big kids too. The natural-born popster — who co-wrote all but two songs — invokes everyone from Wilson Phillips (”Bottom of the Ocean”) to the B-52s (”Fly on the Wall”), with a sparkplug energy and Stevie-Nicks-by-way-of-Tennessee twang that’s nothing if not adorable. Even a rocked-out cover of “Girls Just Wanna Have Fun,” which could have been nullified by its obviousness, makes you OK with the fact that a generation will grow up thinking it’s a Cyrus original. Relying entirely on the full-blooded, all-American guitar, there’s not a single dancefloor beat on “Breakout”: For once, the kids are pogo-ing, not grinding.
