ehhh ... how would he be bitin off kanye when he was the first to work with rick rubin on 99 problems?
In the past 10 years (Since Black Album), Jay aint did nothing with Rick...
Actually make it longer because Rick aint even work on MCHG.. Jay just called him in for a photo OP
He aint get the idea to "rekindle" his relationship with Rick til he heard he was working with Ye on Yeezus.
Face it.. Jay bit Ye on this one..
Just because Jay did a record with him 10 years ago, doesn't mean he didn't bite Kanye on THIS album cycle.
Especially when you look at the fact that Rick aint even work on MCHG at all, and was called in to make the album look "cool"
