Sure 50 Cent’s Curtis didn’t sell as many copies as Kanye’s Graduation, but you didn’t really think the G-Unit machine would stop, did you? Lost in all the hype was yet another mixtape–50 Cent’s “Sabrina’s Baby Boy.” The crew who reinvented the mixtapes returns alongside DJ Whoo Kid more industry beef and exclusive tracks. This installment finds Young Buck addressing the beef with Lil’ Wayne, and expressing his anger that Wayne appeared on Ja Rule’s single “Oh No.” reports that Buck had some harsh words for his former label mate saying, “You have the nerve to call me and speak upon how you having problems and Baby is taking your money. And how right Mannie Fresh is about leaving. And if he responds in any type of way, I’mma end his career ’cause I got it on tape.

Perhaps the only thing more prevalent than G-Unit beef, is the seemingly endless series of leaks coming from Jay-Z’s American Gangster album. Last week the single “Blue Magic” and its accompanying video trailer were made public. Now blogs and chat boards are buzzing with the word that Jay will also release the single “Roc Boys,” due to the lackluster response to “Blue Magic.” This week also finds a photo of the supposed album cover being “leaked.”
