Thanks for pointing out this, i’ve been wondering how to do this.
I’ve been thinking about soundcloud as they have an api.
I could create a site that looks up an artist and seed creating recordings in musicbrainz.
Can you seed the editor to create just a recording instead of seeding a full release?
Yes, but as with the releases, please don’t auto-submit anything
The most standard way would be to write a userscript that puts “Import” buttons by every track (see: Discogs importer, Bandcamp importer, etc).
