Bonus Disc

I don’t quite understand the list you posted, but I suspect having that many inter-linked release groups in the artist page would be even messier?

Maybe the fundamental difference in opinion is that I don’t see a long list of releases in a group as an issue for MB at all.

For what it’s worth, I would rather you added them separately rather than didn’t add them at all, as long as you don’t mind another community member later possible ‘improving’ (e.g. making it fit our style lead’s guidance more) it.
