It was Bob Dylan who implored politicians to “heed the call” of the masses. He asked them not to “stand in the doorway” or “block up the hall”, because, as the song’s title forewarns, “the times they are a-changin’”. Dylan couldn’t have known that one such change would be the way in which his music is distributed and consumed, but his plea to politicians to stand aside to let these changes happen, as many would argue, is still one that they need to hear.
