A lot of pop stars come and go, and aren't remembered. While there are very few female rappers who have made it as big as Nicki. She will forever be remembered by the urban gp. And maybe by pop too. Also Nicki has already outpeaked all of artpop's singles with anaconda (both of their third albums), so we already getting an image of the future.
Lady Gaga. They shouldn't even be in the same sentence. Gaga will be remembered as musical artist with a huge global peak and her artistry makes sure she will be remembered.
And Gaga was called Queen of Pop 3 years into her career.
Yeah I thought that as soon as I posted. But still, being called "influential" is way more important than being given a title which almost every female pop singer receives at least once in their career
