People don't know PFRR like they know PF. SH and Starships are the songs that affected Nicki's brand.
Examples:
My friend was looking at my iTunes, and she looked at PFRR and said she didn't know any of the songs. She clicked PF and was like, oh I know this one yeah.
People like to wear purple at my school (they call it purple thursday) and i heard someone be like "we should have pink fridays" and another person was like "oh yah like that nicki minaj album"
And also, I was browsing one of my friend's iPods and he had Pink Friday in FULL, with no trace of PFRR.
