Would be great to see which artists have no-one subscribed to them, granted that this will be a big list at first.
This report should probably be sorted by number of releases, so artists with no subscribers and a lot of releases are easy to spot. An even better option would be sorting by number of open edits, or by size of edit history, but it might be harder.
