I think we have another label that reverted to his old name..
It's
BMG Japan /
BMG JAPAN.
And they seems to have chosen to same solution: capitalizing their name.
If that's correct for the new NIPPON COLUMBIA, we just have to create a new label.
Also, i was thinking if we could change the organisation linking like the artist linking --> create a warning for labels that got the same name (ex: bmg japan), like we currently have for artists ?
