Roc Nation artist J. Cole, who recently received yet another big co-sign from Nas, has finally released his highly-anticipated debut single, 'Who Dat,' via his website. Although the link to the track was quickly removed, the song made its way to various outlets on the Internet.

On 'Who Dat,' Cole refers to himself as "the little engine that could" and "Fresh Prince, Will Smith to the hood," over the stuttering, bouncy drums and synths, kicking some witty lines with his infectious, sticky flow. The song is produced by Cole himself, with help from longtime producer Elite.

Look out for his debut album, 'Cole World,' which is allegedly dropping in 2010, featuring production by No I.D., Pharrell and Salaam Remi.
