For songs already matched

With the default Update Metadata and Filename Only option SongKong will only try to match songs that have not already been matched to MusicBrainz previously, but it will update existing matches with the latest data or make adjustments based on customer preferences. For example if Update Artwork was disabled when originally matched and it is now enabled SongKong will check for artwork without modifying the releases that the songs have already been matched to. Or if you have changed your file rename mask then the new mask will be applied to these already matched songs in additionally to newly matched songs.

If the option is Rematch then SongKong disregards any matching previously done by SongKong or any other MusicBrainz enabled tagger such as Jaikoz and rematches from scratch.

If the option is Ignore then SongKong ignores any songs already matched to MusicBrainz albums and does not process them any further. Note that songs matched to a MusicBrainz song only or a Discogs album are not ignored.
