But not everyone can relate to J. Cole, Kendrick Lamar, Eminem, Nas, 2pac, Wu-Tang, etc. It's not about relating to the most people or rappers would talk about taxes, dickhead bosses, car payments, etc. 2pac's my favorite rapper of all time, but I can't relate to a lot of the shit he raps about. Same with L. Not sure how many people can relate to snuffing Jesus.
Above all, rap is entertainment. Some call it art. Some call it poetry. I'd agree at times, but in the grand scheme of things it's entertainment and like it or not Wayne, 2 Chainz, Nicki, Ross, and the like are great entertainers. That's why people latch on...also because they're retarded but hey.
