White Privilege Hip-hop?

A comment I found one YouTube by  beckster003:

"White privilege: that black people can popularize jazz (Louis Armstrong) and George Gershwin comes in & suddenly he's the best jazz composer

that Little Richard can popularize rick & roll, yet Elvis Presley is considered the "king" (though some of his songs were stolen from black artists)

that black people can create hip-hop & rap, then eminem comes in and all of a sudden he's considered the "greatest" rapper (not)

realize your privilege as a white american. Macklemore definitely knows whats up"

P.S. This is not a race thing, just look around and be sincere. One Love to all, Peace.
