As soon as I read this, I thought that if I were lucky enough to have a legacy and body of work, but also a reputation for creative integrity, like Prince or Cohen or Bowie, one of the first things I'd want added to my will is that no one should be permitted to take my unfinished works, abandoned projects, outtakes, or demos, and release them for profit (unless I had left clear instructions about a specific project). I know this particular release is being completed by Cohen's son, so maybe they had an understanding before he died, I don't know. But I find the posthumous release gravy train to be apocryphal additions to artist discographies, at best.
