The long-awaited sequel to my Bandcamp Tag Importer:
Taggregator
Quickly import genres and tags from many different sites to artists, release-groups, releases, recordings, and works! Currently I’ve added support for Bandcamp, Discogs, Wikidata, Apple Music, Deezer, Soundcloud, and AllMusic, but if you have another site you’d like me to add just open an issue!
