You could tell Nas and Hit Boy actually became good friends through this process. You can see them in the studio, just zoning out, having fun recording. Having a drink, smokin a bit gettin in that zone bouncing ideas off each other. They also hangout outside the studio too.
Nas seems happy right now in life. That divorce shyt with Kelis is over, his kids are grown, and Nas got the money and status to basically do whatever he wants and it shows that he's in a good space.
As he says on WTF SMH, "Might hop on a jet to Japan, just to eat some sushi, if customs let me in....."
Nas just in that part of his life where the bullshyt is over and he is free.
Having money and being devoid of female drama in one's life does wonders for a man......
