All you embittered, aging, life-haters in the audience should definitely prefer this to Hanson, the MMMboppers' formidable musicianship aside. Jonas Brothers may be prefab kiddie-pop, but at least the tunes have a Maroon 5 modernity, a dollop of smolder that Zack, Isaac and Taylor were way too goody-goody to conjure. "Burnin' Up" will hardly be an embarrassment when one of these kids becomes the next JT in five years.
