I wondered… How often MusicBrainz database updates itself when users enter release? For example, I’ve made entry: https://musicbrainz.org/release/cd5384bc-b5f2-4687-b713-4044603d67ea but when I start Picard and check those files, it won’t find that release at all.
Edit: Shame on me. I was using Picard 2.0.3. When I upgraded, it collected data at blazing speed.
