Guess whoever wrote this has never heard of DC Talk. They were doing Christian rap years ago. They changed their style somewhat and their CD, "Jesus Freak" won a Grammy. It's a great CD.
True, dct were doing rap a long time ago, starting in 1989, but when they broke through on mainstream radio it was after they'd migrated to a more pop, rock, R&B sound. Their rap stuff never got on radio.
