Hi, the artist Morlockk Dilemma re-released two of his albums (Index Finest & Omipotenz in D-Plus) as a single release: Index Finest plus Omnipotenz in D-Plus.
How should this be entered correctly? From the cover it seems, the release group should be Index Finest, but I’m not sure.
A separate release group linked to the other ones with “contains” might be the best.
The 2 album release group is a compilation, by the way.
By the way, this Album+Compilation release group is also affected by the bug that makes it appear once for each Type and Secondary type (recent regression?).
Thanks. And keep the release, I suppose? And is there a way to link the medium?
Erh, yes? Why not? 
Not directly.
The recordings are shared, the release groups are linked.
We have no composite release release-release includes (compilation) relationships (and maybe it’s good like that).
It’s why we need to have a release group in these cases, if we want to show the fact that several “releases” are included in one.
