Rihanna has notched 47.5 million digital downloads, 5.1 million ahead of second-place Black Eyed Peas. Will.i.am, Fergie and co. did notch the No. 1 most downloaded song of all time, "Feeling," which has sold a staggering 7.68 million downloads.

Eminem is the third most downloaded artist of all time, with sales of 42.3 million.

Lady Gaga and Taylor Swift rounded out the top five.

Katy Perry, Lil Wayne, Beyoncé, Kanye West and Britney Spears finished in sixth through 10th place.

"There's nobody really in my league," Rihanna recently told Look magazine. "There's competition everywhere. The whole music industry is competition."
