These two ladies are the most successful acts from the last few years. Ever since they appeared they have been dominating Billboard's Hot 100 chart. Quickly surpassing (#1 singles) older acts and legends, to the point that they both will most likely surpass Mariah Carey, who holds the record for most #1s on Billboard's Hot 100. But who is the queen of this list?
Katy has done it faster and there's no signs of her domination slowing down, so if she keeps up this pace she will slay everyone in the game (legends included)
Of course Katy. Almost all her singles were top 10 hits, without being featuring artist, only with 3 albums, she has most singles that sold 5M copies, Firework sold more than any Rihanna's song and etc.
