Aww, you guys, the Jonas Brothers have grown up! With "Pom Poms" (Jonas Enterprises), Joe, Kevin and Nick take a decidedly more adult pop view, both lyrically and musically, as they combine a marching band full of horns with bits of Bruno Mars' "Locked Out of Heaven" and The Offspring's "Pretty Fly (for a White Guy)." The result is, well, different -- almost unrecognizable, actually, from anything on the guys' last album in 2009 -- though, that's probably the point.
