I’ve now removed all instances of “Jack Hammer” and Piet Botha within my library.
I think the problem lies with you guys not having any Jack Hammer aka Earl Burroughs in your library when testing. There’s clearly a conflation error here in your database or your upstream provider’s:
As you can see, there remain 4 compositions credited to the Earl chap…yet he’s assigned as being from South Africa?
@joel, perhaps this is one for you re undoing the conflation in Roon’s database?
