When Kanye West and 50 Cent released their respective albums simultaneously, the two decided on a sales competition. Apparently, if Kanye's Graduation outsells 50 Cent's Curtis, 50 Cent claims he will never make a solo album again. (I'm not sure what Kanye's end of the bargain is if he loses, so if somebody knows, drop a comment and fill me in).
So what is the current sales counts of each? According to Idolator, West is winning 437,00 albums to 50's 310,000.
