Over the past few days, rapper Chris Brown has been using Twitter to rant that his new CD, Graffiti, isn't available in some major stores - Walmart in particular. He showered his followers with such eloquence as, ""im tired of this s***. major stores r blackballing my cd. not stockin the shelves and lying to costumers. what the f*** do i gotta do," and later adding, "yeah i said it and i aint retracting s***. im not biting my tongue about s else..."Now, days later, it seems that Brown decided that "retracting" these statements was probably a good idea, as his Twitter account has now disappeared, going the route of Miley Cyrus. He had claimed that he visited a Walmart in Connecticut and that the store didn't have his albums on the shelves or stored in the back. However, that particular Walmart has made a statement that they are, in fact, carrying the album - and so are the majority of Walmart stores. Looks like somebody spoke too soon, and decided to quit the microblogging site before he could dig his own grave any deeper.
