It's been five long years since 50 Cent's last album, but anyone anxious about the rapper's financial state can breathe easy: "Rich as a motherfucker and ain't much changed," he declares at the outset of Animal Ambition. Also unchanged are his limitations as a rapper, both technically and in his choice of subjects. The theme here, we are told, is prosperity and its discontents, but he doesn't do much more than flaunt it and berate people for hating his success. On tracks such as Hold On, however, 50 does regain some of the nonchalant menace that made his early material so effective.
