What, you didn't know that "Keep A Knockin'" had been recorded by Louis Jordon in 1939 and went back to the 1920s?
Yes, all those artists did covers or tributes but they were also able to write their own songs and not have to copy other people’s work to pay rent.
The problem today is that bands play who do not have one original song play in clubs around the country. If they want to play a song that they did nor write they should pay compensation.
Or perhaps they should put pen to paper, write a song and stop ripping off actual artists.
