Well, this is a big debate. I think musicians must be paid by playing live, amd not when every human listen a song, do a cover, or listen it in a bar. I think artists should be credited and pay when others use their creation for commercial use. Staff, as always, they will have jobs. You think the staff is all day working with the records, no, they do sound work on live shows too, as welll producers, designers, print guys, etc. People evolve.
