Nicki Minaj, ”Roman Holiday”
Minaj’s alter ego Roman Zolanski is basically just Nicki gone extra manic, with horrorcore influences and an obnoxious British accent. There’s a rousing hook and insistent drum skitter here, but they’re hard to find amid the desperate drama-club poses she insists on striking. C+Kyle Anderson

Tom Jones, ”Evil”
In the recent Loutallica tradition of Silver-Haired Legends Teaming Up With Younger Rock Guys comes this Howlin’ Wolf cover, which also features Jack White and My Morning Jacket’s Carl Broemel. Jones proves he can still holler with the best of ’em, though the whole thing’s a little Vegas-y for the blues. BMelissa Maerz

Katy Perry, ”Part of Me”
Leave it to the pop pro to take her recent divorce from Russell Brand and flip it into an instantly catchy independence anthem. Perry may be single now, but she doesn’t have to worry about finding herself alone on the dance floor. A-Tim Stack
