Cadillac Records

After watching Cadillac Records in class I found myself with several questions. For example, when Leonard Chess paid the radio DJ to play Muddy's song, the woman told Chess that she did not bribe DJ's. How common was it for DJ's to be paid for plays? Granted, we have discussed the payola scandals but just how prevalent was it? Another thing I wondered while watching the movie was how much did one of those Cadillac's cost back then? Sure I would be happy to be handed the keys to a new car, but as an up and coming recording artist, especially as a young black man in those days, I would want to make sure that I was being properly compensated.
