This comparison is just
First off, Beyoncé has had more time in her SOLO career than Katy has. There's a reason why Beyoncé is called the queen. You don't get that title overnight.
Second, all Katy is really known for is crazy successful singles.
Beyoncé is known for iconic songs, successful albums, successful movies ( even though her acting is

) successful perfume lines, and 16 ****ING Grammy's, in her SOLO career alone. All of this done in less than 10 years.
Beyoncé may a little local to some but she still blows past Katy in worldwide impact.
