Mario

Participation of producers Timbaland, The Neptunes, Stargate, Akon and Pollow Da Don, two collaborations, as well as more mature lyrics and Mario's more pleasant vocals is only a part of the factors that make Go one of the year's best R&B release

Though the Baltimore-born singer is newly legal, his enticingly even-toned voice – smooth as R. Kelly’s – transcends teen-pop. Only his age-appropriate tracks remind us that Mario is not a boy, but not yet a man
