Out of a desire for randomness I started playing random artists from the list I have in Roon. And I realise an awful lot, like masses, have been attached to Travis and Fripp. Silent Sorrow In Empty Boats started playing (which is the transition music in Lamb Lies Down On Broadway after the Lamia),
and the credits are So Pitted, Robert Fripp, Theo Travis and Genesis I have to fix this.
I have fixed it. The album by So Pitted had been merged with Travis and Fripp. I edited the album metadata switched it to file data from Roon, removed all mention of Travis and Fripp and then tidied up the Various folder copying all that to the Various Artists. And now it seems sane.
