Jay-Z shocked the world in 2003 by announcing that he was retiring from rap at the height of his success. However, he reversed that decision just a few years later by dropping Kingdom Come in 2006.  Today, Jay is kept plenty busy by managing his vast business empire. He may not be as active in the music scene as he once was. But he continues to do features, and there are rumors that he may be planning a new tour soon. So, while his focus may not be on rap, it seems unlikely he will ever completely retire.
