I was going to do a few more but I think I'm just going to do two more for it.
The reason I choose Mick Jagger for Jay-Z was when talking to DSmooth he mention a comparison of Jay with someone else. In it mention swagger, and it hit me in the head. When you think Rocker Swag who better than Mick Jagger. Jay who not only boast "I invented swag" often said in interviews he wants to be around like how The Rolling Stones are in Rock music. It just fit with me.
