But the good news on Good Girl Gone Bad is that "Umbrella" is a red herring; Most of the album streamlines her dance-pop even further, to the point where I'm not really certain just what makes Rihanna R&B. The great first half of the album is the sort of shit Kylie Minogue should be doing when she comes back: gleaming, über-produced club-pop that puts all its focus on physical movement and never slows down long enough to toy with petty concerns like recognizable feelings. Even in its slower, prettier moments, like the Ne-Yo duet "Hate That I Love You," it's easier to admire the engineering and craftsmanship than to be sucked in by any story the lyrics might tell. Given that Rihanna's voice is a blank, icy, glass-shattering yowl, this album is actually pretty good and I'm surprised.
