In my library i’ve 3 versions of “Seventh Son of a Seventh Son”: the original by Iron Maiden and 2 covers.
Roon groups only the original and the Thomas Zwijsen cover but doesen’t associate the Wilderun cover.
I personally managed the update of the release in musicbrainz and the population of the metadata in the individual files, but Roon doesen’t group them
