Overall its most likely Puff. Hes been on TV involved in so much shit since like 97' I cant even remember it all. Rich and Famous people not apart of Hiphop Culture would know who he is and be at his parties. All his MTV shows that were hits. No one heard of Ciroc before him, then it was in ever rap video, now its a staple when we think Vodka.
Then I'd have to say its between Nas and Pharrell. After that prob Jay -Z & Khaled. I honestly dont know how you have Jay as #1 in terms of influence. His biggest influence is people drinking Ace. Everything else he mostly just jumped on a wave that was already happening. Cut it out with that he killed autotune shit, it was already starting to die down and autotune songs still came out and was getting play after he dropped that shit.
And for anyone wondering why i have Khaled and Jay together is because, think of how this fat weasel somehow influenced music since like 2005. He lowkey shifted the style.
