Artist: Akon Track: "Right Now (Na Na Na)" Album: Freedom Listen

For the past two years, Akon has replaced Nate Dogg as the crooner every rapper wants on his track. He's done great work with Young Jeezy, Wyclef, Lil Wayne and others. His solo material has always suffered, mostly because you can't make a hit with only a slick chorus on repeat. Evinced here is the fruit of learning from masters. The beat is strong, and the Atlanta artist stretches his vocals to new heights (and lengths).
