Her music on Pink Friday is more Pop than her earlier works, but I don't understand why people are acting like she is as Pop as Katy Perry and Ke$ha.
I don't recall a Katy/Ke$ha song sounding like M4L, Fly, Dear Old Nicki, GFLD, or even Super Bass. These songs all have pop elements, but are still delivered in rap form.
People are forgetting that Nicki still has songs like Roman's Revenge, Blow Ya Mind, and Did it on'em.
