Idk. His marriage to beyonce is a major factor in keeping him relevant Beyonce doesn't need Jayz at all. She's 1 of the 3 biggest artists on the planet next to adele and rihanna. Everything she does his name is attached to it why is this? To keep his name relevant to the "pop" audience. Other than hip hop fans no other group will be checking from Jay.
They keep each other relevant. What would Beyoncé's Lemonade be without Jay Z? He's not featured on it, but without him, there's no narrative. A huge part of the media's fixation with that album was the speculation that she was talking about her marriage with Jay Z. I'd concede that Beyoncé is the biggest Pop star on the planet, but she and Jay benefit from each other.
