Right to resell downloaded music challenged in US court

Must remember to keep an eye on this court case. According to ‘The Tech Report’, Redigi is a company that makes money as a middleman re-selling iTunes music and Capitol records is suing them for it. I’m hoping ReDigi wins this case. Honest question, why should Artists or record companies make money of the re-sale of music? You don’t give Ford a cut when you sell your old car, why should artists or record companies get payed twice or even more?
