50 Cent (declaring he would quit performing if Kanye West sold more albums than him): Let's raise the stakes. If Kanye West sells more records than 50 Cent on September 11, I'll no longer perform music. I'll write music and work with my other artists, but I won't put out any more solo albums. 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.
