Fran, I don't think it's the big deal if you happen to share a piece of
music that "accidentally" contain such a style, even if it's legal by
law or not.
But, if it's done by i.e. use of a e-mail list to reach between two
and maybe hundreds of "members", would you still call it to share it
with a friend?

Roger, by use of i.e. mp3 you'll also be able to share your music to
other than the users who have the same instrument model as yourself,
as long as noone claim the copyrights of the tune......

Oh well, guess what, whatever way we turn the body, the butt will be
behind the front.
