“buying music by the copy” is over???
But then how will the producers of copies get paid if people make their own copies?
I know, perhaps the producers of copies will join musicians and start helping them make and sell music?
Anyway, even if they don’t, even if producers of copies cease trading and find alternative occupations, the producers of music still have a product that remains in high demand.
The market for copies has ended. The market for intellectual work resumes.
So sell music, not copies.
