The album's production is almost over, however, and Nas said Jermaine Dupri and Diddy will be helping him to close out.

"It's in the developmental stages," he said of the tracks Diddy is bringing to the table. "The potential could go anywhere. I'm writing a lot of sh-- down, and it just sounds crazy.
