pub fn release_groups(response: &Json) -> Vec<Candidate<ReleaseFacts>>Expand description
Release groups, as /ws/2/release-group/?query=…&fmt=json returns them.
Groups rather than releases, deliberately: a release group is the album, and every remaster and reissue of it is a release inside that group. Asking about releases would answer with one edition among twenty and call it the album’s date.
