Why is Beyonce's sales being compared to Rihanna's? Beyonce has 4 albums while Rihanna has 8. That's an unfair comparison. And considering Rihanna hasn't taken a break from the music industry since 2005 and releasing single after single, sales are irrelevant
anyway, she'll surpass Beyonce only due to her excessive working. Let's remember that Beyonce isn't as active as Rihanna in the music industry
