Well, here comes a rather interesting thing. As I understand copyright on music, TV and film are 50 years in most countries (some are 99 I believe) and as long as you don't supress the source it's public domain.
During the time of Mozart, Beethoven and the "big boys", there was nothing more than paper and ink, so we can of course argue that that music is like books. But anyway, we will very soon enter a time when a lot of recorded media becomes public domain. This would include movies, cartoons, music etc.
How should this be tackled in the future ? When the musician in question is long dead and gone, shouldn't the younger generations be able to enjoy it ?
Another interesting example is the "underdog" concept on old games. The old DOS based games are traded freely over the net nowadays, with nobody have any problem with it, as long as no commercial interest is there.
I think that we need to make sure that we don't lose the old "culture" due to some disgruntled media directors still hoping for the big score.....
