Consider the case of "I Will Always Love You", written and originally performed by Dolly Parton but made globally famous by Whitney Houston. I mean, Parton is a pretty legendary songwriter, but let's be honest, the only reason that song was played over and over on the radio was Houston's voice. When Houston died and the song was again put in rotation on the radio, is it really fair that Parton received all the benefit of that and Houston's estate nothing?
