I tried Gerald Finzi. It shows Vaughn Williams with and without Ralph, mixes composers with performers, and adds rather unrelated composers. It also adds "Clocks and Clouds". This is either an instrumental trio that creates "epic" music, or a composition by Ligeti, neither of which is in the same category nor has any relation musically to Finzi. And it adds "Yak Bondy", which is inexplicable.

I guess it just does things when there's not much data, but that makes it practically useless for discovery.
