Use the file hash to import metadata (name, tags...) from wikis like musicbrainz.org, stashdb.org (NSFW), anidb.net, themoviedb.org, thetvdb.com, vndb.org, alternativeto.net, opencritic.com.
It would probably be best to have a companion website that works for general media instead of having to import metadata from so many different sources.
