Joe Jonas - 'Fast Life' (10/11)
When the middle Jonas Brother started working on his solo debut last year, he had "a Michael Bublé-type singer-songwriter record" in mind. But hot producers including Danja and Rob Knox – both former Justin Timberlake collaborators – guided him toward R&B-flavored dance tunes instead. "As me and my bros grow up, so do our fans," says Jonas, 22. "I think they're ready for something new."
