Yas cause Umbrella wouldn't have gone #1 without JAY Z, What's My Name? wouldn't have gone #1 without Drake and We Found Love without Calvin Harris.
Rihanna gave Eminem the last two #1's. I guess Rihanna her power?
S&M would have been #1 without the remix if only she performed.
You can say what u want, the fact that the Queen of Pop is slaying all your faves (unless they're The Beatles)
