Rapper feuds only come in one size – extra large. Kanye West and 50 Cent’s epic battle of the MC’s is no exception to this rule. When 50 Cent heard that Kanye West’s new album “Graduation” would be coming out on September 11, the same day as 50’s album, “Curtis,” a challenge was issued. 50 claims that if Kanye’s album sells more than his own on Tuesday, he will retire from rapping as a solo artist. E! Online reported that 50 said, “Put it like this. If Kanye West sells more records than 50 Cent on September 11, I’ll no longer write music. I’ll write music and work with my other artists, but I won’t put out any more solo albums.” Originally, the two albums were not intended to drop on the same day. “Graduation” was moved up a week while the release of “Curtis” was pushed back several times to make edits on the track list. While 50 has been using every opportunity possible to assure both his audience and himself that his album will come out on top, Kanye has been taking it all in stride. He even said that 50’s new single “I Get Money” is his new favorite song on New York’s hit hip-hop and R&B station, Hot 97.1. Adding to the controversy, both 50 and Kanye have agreed to rap singles off their new albums on BET’s hit show “106 and Park.” Not without a sense of humor, BET has hired ESPN announcer Stuart Scott to give the play-by-play of the rappers’ performances and statistics. The rap-off took place on Tuesday, the release date of the albums, at 6 p.m. Some people have gone as far as to call it the “lyrical Superbowl of the century.” Exuding confidence as always, 50 told 106 and Park to “just make sure Kanye West shows up.” In response to this statement, Kanye said, “How could I not come to ‘106 and Park’ on the day my album comes out? I’m definitely coming.” As of Monday night, iTunes preorder sales have Kanye leading the way at the number two best-selling spot, while 50 is not too far behind in the number nine spot. Interestingly, their singles, “Stronger” and “Ayo Technology” are sharing the same ranking as their album counterparts. Meanwhile, 50 continues to speculate that his album will beat out Kanye’s in the long run. He explains that the only reason anyone believes that Kanye will outsell him is because Kanye is the underdog. According to BET Online, 50 said, “They would like to see Kanye West give me a problem, because I’ve worked myself into a space where I’ve become the favorite. Everybody roots for the underdog when he goes against the favorite.” The world will find out whether or not this is true soon enough, but in the meantime, 50 remains confident. As for Kanye, he doesn’t seem particularly worried about the upcoming competition. He even went as far as to say, according to Fox News, that his “biggest inspiration and biggest competition is Justin Timberlake.” According to Billboard, Kanye’s album sold 437,000 copies on Tuesday, while 50 sold only 310,000. But only time will tell if 50 will honor his agreement.
