For songs already fully matched
This option decides what do if reprocessing songs already matched.
Ignore songs already matched to MusicBrainz or Discogs
This option can be used to skip over songs that SongKong has already matched to MusicBrainz or Discogs with the Fix Songs task. If an album has already been matched to MusicBrainz or Discogs then it is probably not neccessary to try and match to Bandcamnp as well, so with a large collection enabling this option could save us a lot of processing time.
If song already fully identified we can choose if it should be ignored, metadata updated with any new metadata using existing match or rematched as if not currently matched.
