Something odd is happening here. Perhaps I can offer a piece of insight.

APRA is the Australian music copyright organisation (https://www.apraamcos.com.au/)

ECAD is the Brazillian version.

VCPMC is the Vietnamese equivalent.

Not sure about the others, but basically these are the people with whom a composer registers their work. These organisations work together by forwarding royalties collected within each territory to their rightful owners.

I am a member of APRA and very much doubt that someone got away with registering a Beethoven work as their own.

Very curious indeed. I have no explanation.

[Edit] You are only meant to register your work in one territory, so it is odd that this 'work' would be registered in four of them.
