T.I.‘s renamed album, No Mercy (previously King Uncaged), is set to hit store shelves in December, but first, here’s the newest single from the project, “Get Back Up” with Chris Brown. As you probably already know, T.I. will not be a free man when the album is released. He checked back into an Arkansas prison on Monday to begin serving a 11 month sentence due to his recent probation violation in September.
