As has been stated previously, the Estate won’t release everything in the vaults based in large part on the choices Michael himself made during his life.
If we released demos by themselves, they would not show Michael in his best light, and would not be commercially successful because they are, by definition, unfinished. While releasing unfinished work may be appreciated by the fans, it would not be the way to introduce Michael to new fans who should hear Michael at his best. That is certainly how Michael decided what to release and we believe that is what he would want us to do. And even among the fans, we see disagreement on whether unreleased material should be finished to make them commercially viable or not.
Michael had several philosophies that we use as guides. One of those is, “The quality goes in before the name goes on.” Just because something exists doesn’t mean it should be made public – and sharing with the fans is the same as making it public.
Just because something has been leaked by a fan doesn’t mean that it is something which should have an official release. The fact that it is leaked means that Michael didn’t intend for it to be shared by whomever he may have trusted with it in the first place.
