Did JRRT encourage new ME stories?

However, if the defining criteria of acceptable writing about Middle-earth by another authors is this issue of "authenticity" -- lacking the genuine Tolkien element of autobiographical mind-mold (if not leafmold)--then why doesn't this issue of being genuine apply to Tolkien's own acceptance of his mythology in other art forms by other people? Autobiographical genuineness clearly didn't matter to Tolkien there.

He'd no objections to songs and stuff as he worked with Donald Swann, but I don't know if he'd have gone much for the music in the current musical as he was known not to be fond of pop music at all, as you might expect for someone born when he was.

But somehow I don't think the 'authenticity' issue is of any matter when someone is adapting a story that's already been written by Tolkien. What are they gonna do? Hop in the nearest Tardis and go back and change details of his life?
