The Navy trying to speak about impact when Riherp has none. What are her iconic moments and performances again? What TV records did Riherp break? How fast did Riherp's shows "sell out"?
Chris Brown his debut sing Ram It! went #1 in 2005. Pon de Forehead only got to #2 in 2005.
Chris Brown got a #1 album with limited popularity & backlash with his 4th try . Ram, with her WW popularity & pop hits, got a #1 album for the FIRST time just last year after 7 tries.
Chris Browns debut album sold more than every Rihanna album in the US except for one.
And I don't know why you're trying to come for Avril, her last 'flop' album sold 1.7 million. That would be considering more or less successful for Rihanna.
