Katy was never on Brit's level to begin with, not comparable. Katy never even had a Gaga era of impact, she will never know what it's like to be as famous as Brit/Gaga or Taylor
Chris has a huge huge amount of Urban hits. I actually hate to say it but he's gonna go down on R&B Legend level.
He has the Usher amount of hits on Urban. And he basically was the Usher of his generation in that he slaughtered every other R&B Male. What R&B males rival Chris Brown this decade? August Alsina? Miguel? Frank Ocean? All these guys with 3 hits.
Chris is NOT an R&B legend. He's an icon of the genre, sure.
if Mad Men's reaction to Marylin's death was accurate to real life Marylin was way more than just an icon. I doubt you'll see young women across america crying when Kim K dies
Chris Brown has 500 hits, every R&B Male debuting next decade will cite him as an influence, and since he's debuted there's literally been no other R&B Male who's debuted who's had even half the hits as him.
Trey Songz was his only real competition at one point and he has 5x less hits and the only time he was ever able to go mainstream in his career was in 2009 because nobody wanted Chris Brown anymore at the time. The peak of his career is due to Chris Brown.
It's actually kinda a Nicki with Female Rap thing. Everyone wants to hate them and they're annoying but they'll still be considered R&B and Rap Legends because no other Female Rapper or Male R&B Singer was able to compete with them.
Beyoncé is the current Queen of R&B and Usher is the current King of R&B.
The throne was R. Kelly for his generation, to Usher for his generation, and then Chris will be the King of R&B of his generation. Another reason he's an R&B legend.
