According to Neon Limelight (by way of Billboard), nine No. 1 singles in five years means: Rihanna [has] the most No. 1′s of any artist in the 2000′s, she’s the only female to top the chart four times in a single year, and it’s the first time an album’s first single tops the chart after its second single. Rihanna's second single from LOUD, What's My Name featuring Drake, topped the Billboard Hot 100 two weeks prior.
The site also commentates that though LOUD landed at No. 3 in U.S. album sales this week, the album sold more units in a week than any of her other discs, pushing 200,000+ units.
In response to the good news, Rihanna tweeted: Only Girl is no. 1!!! HOLY FUCK!!! And thx to u guys, I've had the biggest first week of all my albums so far! #whosloud???? We are bitches. She added an hour later: Congrats to RihannaNavy! We breakin our OWN records!!! 9 no.1's baby...We got the #CenturyOnLockWho's badder than yall??
My Response!: That's right, RiRi! Do that sh!t!
