OK Go's songs are a lot like their brilliant viral-hit videos: cute, ingeniously crafted and entertaining, but not something you need to experience more than a few times. Their fourth LP veers from Prince-ly falsetto pop ("I'm Not Through") to sweeping alt-rock ("The One Moment") to pretty, acoustic reverie ("Lullaby"), with Flaming Lips producer Dave Fridmann adding a bright, inviting polish. But the songs aren't quite memorable enough to hold your attention, or make you wonder if there's anything going on beneath their expert exteriors. A serious New Order crush comes through on "The Writing's on the Wall," which has an awesome eye-tricking video. The song itself is pretty OK too.
