Update: It's Durt Boy, not Dirt Boy. He appears to be an artist signed to Block Entertainment.

Updating a previous story, the bonus tracks that are being sold with "Hustlenomics" are as follows.

The Circuit City exclusive is "Coloso" featuring Gorilla Zoe. The Best Buy exclusive tracks are "Hold Up" featuring Durt Boy and "Do It" featuring Durt Boy.

Finally, if HMV is correct, it seems that the Japanese version will have "Hold Up" in addition to "It's Goin' Down", as previously reported.
