I just read an article on HNHH about why a Cole and Kdot collab album wouldn't work. Basically Cole and Kendrick aren't on the same level.
"KDot is Langston Hughes, Cole is Dr. Seuss. And that's not a knock on Cole. Born Sinner and Forest Hills 2014 are both platinum records for very good reason. Plus Dr. Seuss is a damn legend. But to place genius simplicity with sprawling rap virtuosity is a little brutal"
I don't see it that way.
