Much of the "problems" associated with the flux are because of wrongheaded decisions and a bullheaded insistance on defining the market rather than following it.
I was looking at the back of a 1982 British REISSUE of James Brown Live at the Apollo (from 1962) and there is a little "Home taping is killing the industry" logo. They are still making billions every year; nothing died.
Resale of OLD albums (I bought that one 'used') "kills" the industry as well because they don't see a dime off of those sales.
"defining the market rather than following it"
good observation
