Where or if to draw a line, eh? I expect there could be songs that I would want to disappear - there must be songs so foul that I would want them to die. I suppose we all draw our own personal lines & there will be songs that I would rather preserve that someone else would feel too apalling to be kept & vice versa. So I guess my opinion is that one should help to preserve & pass on whatever one feels is worth preserving & that one shouldn't expect to be able to prevent anyone else doing the same.
I'd reserve the right to make my opinion known though.
