In just under five years, Rihanna has made music history. The pop star is the youngest artist to ever have ten No. 1 songs on the Billboard Hot 100, a feat she achieved this week with "S&M." Surely, sales of the just-released Britney Spears remix helped tremendously.

RiRi stands as the ninth artist overall, and fifth female, to reach the goal. Congrats.
