Before Kid Cudi left G.O.O.D. Music, he and 'Ye were lending verses to one another like it was nothing. The former boss/mentor and protégé team have a slew of collaborations including "Erase Me," "Welcome to Heartbreak" and "Guit Trip." And let's not forget Cudi was a staple on Yeezy's G.O.O.D. Friday series. But Cudi announced he was going a separate way more than a year ago, and while he maintained that "everything was cool," (and Big Seanconfirmed it), the boss himself has not yet addressed it.
