My grandfather had told me a story of a guy he knew in must of been the 50's or 60's and this guy was an up and coming musician. And the guy was on his way to being a star. So one night this guy was on the road and at a hotel and some mob guys came to his room. They wanted him to sign a contract giving them lots of his royalties or something and he refused and my grandfather said he never became a star and they stopped playing his music on the radio.
