I had assumed that this meant that folks could 'edit' the ABC and let other folks see the result. If it's copyright, should I now remove the ABC from the post? Not at all. The music company isn't worried about this sort of usage but only if someone tries to make money from the song. So don't go putting it on your next CD or Spotify.
