Sounds like Jay is imitating the "nowwww, crooowwwwn" delivery Drake was doing on "Days in the East".
I know I might be reaching but anyone else think Jay and Kanye might be sending subliminal jabs back and forth? First Kanye was showing up in interviews almost admitting defeat in the music world and proclaiming Drake as the new king, then making appearances at clubs and at each others' shows. The first time I heard that "Drunk in Love" remix with Kanye, it felt like that "fukk THEM" at the end was to Jay & Beyonce as a couple... I know some of you are gonna think that's the ultimate Dhalsim reach, but in the context of the song it makes sense. And maybe it's something Jay will pick up on. Now he's on this track imitating the Kanye scream shyt too.
Maybe?
