I keep running into this issue where I can't find the specific release of an album using the auto-tag window, even though I can easily look it up on Discogs/MusicBrainz and find an exact match. But what would help is being able to input a release code from Discogs/MusicBrainz on the auto-tag window and find that match, in a similar manner to how you do it in foobar2000.
For example, I've found this album (that I own and have ripped) on both Discogs and MusicBrainz, but I haven't managed to find ANY releases in the auto-tag window that match:
Discogs release:
