With the second single from the forthcoming Loud, Rihanna has created a perfect little tropical storm: Over dark, humid synths and swirling snare skitters, she's in full-on Caribbean-queen mode, dialing up her islander accent and rolling out a to-do list for any adult male seeking entrance into her chambers: "Hey, boy, I really wanna see if you can go downtown with a girl like me," she sings, kicking off the chorus. Her former fling Drake further steams things up with a little, um, math: "The square root of 69 is 8-something," he offers, sounding like the nerdy guy in a fraternity. The end result isn't quite "Umbrella," but between its star power, sex appeal and the impeccably sculpted chorus, "What's My Name" seems like it's destined for ubiquity. Even Chris Brown has tweeted in support of the song's dopeness. For all his faults, Brown at least knows who's on top these days.
