Taylor and Rihanna are both massive icons and superstars, and have both grossed over 300m cumulatively on tour at 25.
They have each sold close to or over 30m albums, and over 70m digital tracks in the US alone.
Plus the crossover artists each rule a different side of pop, POP/RnB and POP/Country
Do they currently rule music?

Plus they are both massive on social media
Rih rules youtube, 2nd on fb and taylors 2nd on twitter (amongst girls)

No Bey is on the top RIGHT NOW and Gaga is there too overall these years

Neither are superstars specially not Rihanna

Taylor is bigger but Rih is doing ok.

Taylord is bigger in the US, Rih - overseas.

Taylor and Rih have both sold more albums than them (especially adjusted), let alone singles tbh

If rihanna isnt one of this decades superstars then who is..

If R8 is successful, then yeah.

And what would a person like you know about supersatrs, dear ?

Yes Taylor is the Queen of the US and Rihanna the Queen globally.

I'm guessing cuz he used a nickname

Beyonce, Katy Perry & Taylor Swift right now, since Rihanna isn't releasing anything.

I honestly don't know
They are the biggest popgirls right now tbh
and they will rule fall this year

Global Queen Rihanna and U.S Queen Taylor

Shes not on top of anything

Biggest lie ever heard on this site.

Lets wait until the VMAs.

And she still had a #1 with no album out...Who else ?
