You totally missed my point and I never said copyright should be perpetual - Life plus a bit at most.
You said if something was unsuccessful then it must be because it was crap. I was making the point that because a work is unsuccessful in the creators time doesn't mean it's crap; ref. Van Gogh
Contrary wise; because something is successful doesn't mean it's good - Have a read of Guy N Smith for proof; or you could just take my word for it and save yourself some pain.
