If you have digitized your Music collection, then there is a real boon in not just identifying your songs but maintaining the links to the Music database they have been matched to. For example you can list your collection on Discogs, you might want to just share your music preferences or you may be interested in trading some of your records.
This is why SongKong and Jaikoz do not only store basic metadata like Artist, Album and Title, but also fields that identify the correct MusicBrainz/Discogs data such as the artist(s) and release.
With previous versions of SongKong songs an attempt was always made to match to MusicBrainz before matching to Discogs. But now in the latest 3.24 release you can disable MusicBrainz matching and only match your songs to Discogs, just disable the Search for a MusicBrainz match.
Now you can even disable the Acoustic fingerprinting stage, but even if you are only matching to Discogs then SongKong can still make use of acoustic fingerprints, so we do not usually recommend it.
And of course you can just match to MusicBrainz and not update or match to Discogs by disabling Update from Discogs and Search for a Discogs Match.
