SongKong 3.9 released on 28th January 2014

Better Discogs Artwork Coverage

Discogs has a concept of primary artwork and secondary artwork, primary artwork contains the front cover art and secondary artwork was used for other images such as the back cover or sleeve inserts. It used to be that an editor could specify whether an image was primary or secondary. But now when editing the first image is always considered the primary image and all other images are secondary images, this order can be modified by dragging and dropping the images in Discogs to make a different image the primary image

However the Discogs data dumps contain many releases that only contain secondary images and no primary images. The precise reason for this is still unclear but whereas SongKong previously ignored secondary images meaning no Discogs images was found for these releases SongKong 3.9 now makes use of the secondary image if a release contains no primary image but does contain secondary images.

For you this means even better image coverage

Improved Matching

For multi disc releases grouped one folder per disc SongKong could incorrectly match just one of the folders to a MusicBrainz release and not the others if MusicBrainz only contained a single disc version, even if  the complete release was available in Discogs. Now when matching multi-folder groupings if it fails to match the folders to MusicBrainz SongKong attempts Discogs match before breaking into subfolders and matching each folder to MusicBrainz only if no Discogs match is found.

If you have iTunes configured to make a copy of all songs added to it (the default) then any songs with no metadata are added to the Unknown Artist/Unknown Album folder. SongKong now realizes that this folder does not represent an actual album and therefore should be treated as one.

A silly assumption crept in somewhere that if all songs are by different artists then it must be a Various Artists compilation but this is often not true such as in this album - and this prevented SongKong matching albums when it should have.

Various Fixes

We also have a host of bug fixes across  various parts of SongKong, full details at the Issue Tracker

SongKong 3.8 released on 14th January 2014


We have improvements to the Windows installer, its now a self-extracting archive


If your database was corrupted you could try and recreate it by using Empty Database but this did not always work and you had to manually recreate the database folder, this is now handled by SongKong.

Matching Improvements

There are some bug fixes and improvements to matching itself. SongKong was not always doing its Acoustid double-check to ensure that songs had not been matched to a song with a title that didn't match the songs Acoustid, this is fixed.

SongKong had an issue when matching fields with a quote in it, this could prevent potential albums being returned, now fixed.

SongKong tries to weed out duplicate songs when matching a folder of songs to an album, but it was incorrectly identifying songs with the same name but actually different track lengths as different songs, such as the two versions of L.O.V.E on this release.

Improved Match Song only to both match more songs, and to be careful when matching songs when you already have a song with a different title.

We also fixed a bug that when renaming files from multidisc releases from a folder per disc to one folder per complete album we were left with folders that should have been deleted.

Report Improvements

The Fix Songs report now comes with extra instructions on how to navigate it, and errors are now timestamped

SongKong 3.7 released on 4th January 2014

This release improves Classical Release matching plus some other reliability improvements including avoidance of deadlocks

Very Long Song Titles

Classical releases can often have long titles because according to the MusicBrainz Classical Guidelines if they are part of a work they should contain the Work title in each song title, for example here. And Operas should contain each act or scene as in here. This means when matching existing song titles it takes longer because there are more words to match, it is also harder to match because these guidelines don't reflect as accurately what is written on the cover as for non-classical releases.

Very Large Releases

Because many classical composers catalogues are out of copyright it is inexpensive for music publishers to release large box sets  of a composers output. One such example is the 100 CD Complete Works Beethoven release. Its actually too large to show reliably in MusicBrainz so instead I show the results of a search .Trying to match songs to large releases is invariably more time consuming than smaller releases because there are so many permutations to consider, actually expotentially more.

These issues plus other fixes are listed in the Issue Tracker

SongKong 3.6 released on 17th December 2014

An attempt to solve a problem with occasional deadlocks when matching groups of songs.

SongKong 3.5 released on 12th December 2014

In previous releases the main focus has been on improving the Fix Songs task but in this release we wanted to review other part of the application application, especially Delete Duplicates Songs

Delete Duplicate Songs

First of all we found some bugs in Delete Duplicates that have now been fixed.

The help for Delete Duplicates has been completely rewritten to give more detail and make more sense for non-MusicBrainzers and additional checks and balances have been added to make Delete Duplicates work better in Trial mode.

The we added a new option to Song is a duplicate if has same called Same song (metadata only). This is very similar to Same MusicBrainz song only for finding duplicate songs without being concerned about albums, but without the need to match the songs to MusicBrainz first (although we would always recommend using the MusicBrainz based options whenever possible)


Help has been edited, including simplification of the terminology such as using Album instead of Release and Song instead of Recording. We have added a Pdf version accessible from the Help menu for some bedtime reading, but seriously the Pdf version works well if you want a paper copy of the SongKong manual.

Fix Songs

But despite what I say at the start of this post we have made some improvements to FixSongs as well, these include some major performance improvements based on improvements we made in Jaikoz 8.

SongKong 3.4 Released on 16th of November 2014

This release is full of improvements to the matching process.

SongKong now does a much better job of handling multiple albums without metadata in one single folder. Previously if you had Only allow match if all tracks in album were matched enabled it had difficulty matching multiple albums contained within a single folder unless they had some existing metadata. The workaround was to disable the option but this then allowed SongKong to match partial albums, possibly not the desired outcome. Now in this release SongKong can derive metadata from the songs Acoustids and group and match the songs accordingly without having to disable the above option.

Overall SongKong is better at matching albums, before this release it would try and match a grouping completely to one album, if that failed and depending on user preferences it would then match each song one by one. Now before resorting to song by song matching it trys matches partial groups to a release. This means results are split over less albums, and it speeds up the matching process because it is quicker to match a group  of songs to a release in one go rather than song by song

There are some super larger releases in  MusicBrainz and Discogs, these are usually Box Sets of the complete works of established artists. Matching songs to these larger releases can be time consuming and give the impression that SongKong has stopped working. A number of improvements have been made to prevent SongKong spending too much processing a group of songs, and a Still Alive progress bar has been added to show that SongKong is still working 

Full details of all issues fixed in this release can be found here .
