Then I added the album I was looking for: “Half About Being a Woman” from 2013 (release group, release and recordings).
Only then I found out, that there’s an artist Your Smith - MusicBrainz with the album I was looking for. Seems that since 2018 the artist is named “Your Smith” (which I wasn’t aware of).
What’s the best way to handle this? Should I delete the newly created release group, release and recordings?
What’s with the artist Caroline Smith - MusicBrainz? Should it be deleted too? Its existence was the main cause for this mess and it’s already present as an alias for “Your Smith”!
I’d merge release group, release and recordings. I would use artist credits if necessary (if Caroline is used on release). I’d merge Caroline Smith in Your Smith and use aliases.
I also found that Gigamesh release looking at the “Caroline Smith” edit history. Seems the duplicate artist was introduced for that release - probably the editor wasn’t recognizing “Your Smith” as the appropriate one (just like me). So how should this be handled?
A disambig is always a good idea for Artists whose names aren’t large primary numbers.
In this case there is a least one other Caroline Smith ready to mess up the clarity you’ve created. A disambig can help. Role, genre, dates, geographical tag - whatever will steer a hurried editor away from mis-using Artist Your Smith.
