It’s time to let go of “Mmmbop” and admit that the Hanson brothers have grown up and are now adult performers writing songs for more mature audiences. Their shameless pop hooks still lead the way, but it’s with a songcraft that would be the envy of many performers who are struggling to make an impression without losing their bad teen-pop reputation. “Waiting for This” is an immediately likable piece of radio-pop. The guitars crank out economical riffs. The hookline is sturdy and the ensemble vocals create a party in the making. “Thinkin’ “Bout Somethin’” adds horns and tilts towards the band’s R&B interests. “Kiss Me When You Come Home” is more modern R&B. They’re natural pros and no one’s ever going to mistake them for a rough n’ tumble act. Whether the Hanson name helps or hinders the band is debatable. It depends on what you expect. But if you’re expecting slick, smooth, virtuoso pop performances, you’ve come to the right place.
