Big Sean and Kanye West's business and musical relationship appears to be over.  

Sean is off GOOD Music and claims Kanye owes him millions.

For Kanye's part, he said signing Big Sean was the worst thing he'd ever done.

Sean discussed Kanye on the Million Dollaz Worth Of Game podcast and broke down what a taskmaster Ye is in the studio. [Jump to 31 minutes.]

 “Kanye can be very hard to work with," Sean said “Kanye will have you re-do a verse 10 times and not use them.”

Hit-Boy, who was on with Sean, agreed that Kanye is difficult in the studio.
