Once upon a time, 50 Cent challenged Kanye West to a "who can sell more" contest, promising to quit the rap game if he did not out pace 'Ye when they dropped their albums on the same day in 2007. It was a battle for the ages, even landing the cover of Rolling Stone. Both rappers were at significant heights in their careers. Ultimately, however, numbers don't lie. First week of sales had 'Ye nearly platinum with some 957,000 copies of his Graduation pushed. 50 had about 300,000 less with Curtis.
