I have a lot of albums files with partial metadata (album and title always) saved, I usually update them with musicbrainz but unfortunately I have to search them one album at the time.
Would it be possible somehow automatically select the album tracks, a kind of partial CTRL+A, to speed up the process ?
I would not recommend this workflow, as it will result in a high number of incorrectly assigned metadata.
There is currently no known process that can automagically find the album with the 100% perfect match and also the correct sort order in your local tracks.
