// Because the MusicBrainz API doesn't return a name or label for a link, like
// for example {"name": "Bandcamp", "url": "https://bandcamp.com/..."}, we have
// to figure out a name for each link. So all the known links are simply saved
// in a JSON file where we have a regular expression to test for and a
// replacement name to use instead. And whenever a link isn't matched to any we
// can just use the host name of the URL like "bandcamp.com".
