SongKong Support:How to get Help when you have a problem

We provide ourselves at JThink on providing the very best customer service. Every suggestion is considered and every problem investigated, SongKong is being continually improved. Over the years we have implemented more systems to help with this, so thought it was time to provide an update.

Types of Problem

Support problems can be split into three broad categories
  1. General help on how to do something
  2. Suggestion for improvement or new feature
  3. Particular problem encountered, SongKong not working as expected or giving errors

User Forum

The first two cases are best resolved on the Jthink User Forum
we try to respond within 24 hours 7 days a week, but by posting here  you often get help from other SongKong Users. The SongKong Questions sub forum is usually the best forum to use. Facebook and Twitter are not monitored as closely so are not such a good choice as the forum.



Create Support Files

If your issue is in the third category the first thing to do is run Create Support Files. This is available from main menu in Remote Mode and the Help menu in the desktop mode.

First you need to enter a summary of the problem then this will upload SongKong log files and the last five SongKong Reports to the JThink server and then notify JThink that the support files have been uploaded.

The logs files will show more details then the Errors and Warning section of the report. If your problem is how songs were matched/renamed or moved it is much easier for JThink to resolve your problem if we can see your reports.


If you need to send additional screenshots then email can used, but this should only be done after sending support files

Request for Additional Information

We may ask for additional information to try and resolve the problem. If the files are small you can use email, if they are larger such as music files then we recommend you use a file hosting service such as Dropbox (free for upto 2GB of data)

Remote Login

Occasionally we may decide that remote access to your computer would be the best approach. In this case you would need to install the free Team Viewer then by Email we can agree on a suitable time to remote connect, this usually would take no longer than 30 minutes.

Existing Issues and improvements

Whilst SongKong is not an open source project we try and be as open as we possibly can. As part of this you can view all the outstanding bugs and improvements at our JIRA tracker. Green issues are improvements/new features and Red issues are bugs, you'll be pleased to know most of the issues are Green.

SongKong 5.9:Improved Song Identification and Performance

SongKong 5.9:Improved Song Identification and Performance

We are pleased to announce SongKong 5.9 with improved song identification and performance.

Improvement to Albunack MusicBrainz Disc Ids 

In SongKong 5.7 we introduced Albunack Disc Ids, this provides a way to identify complete albums without requiring acoustic fingerprinting, both speeding up song identification and increasing the number of matches that can be found because it was able to find albums without known acoustic fingerprints or existing metadata.

We have now improved this algorithm to get more matches. Testing against a 1200 album test set with SongKong 5.7 could identify  501 albums just using Albunack Disc Ids, with SongKong 5.9 that figure goes up to 570 albums, an improvement of 13 percent. (After subsequent matching with AcoustIds and metadata we can identify 1108 albums.

Better Performance

We have made a number of further performance improvements. Many of these improvements reduce cpu usage so have most impact on slower/single cpu computers. Such computers should see a 30% increase in performance.

  • SongKongs internal database has been optimized to reduce the number of calls made to the database 
  • Scoring algorithm has been optimized   
  • AcousticBrainz data can now be looked up per album instead of having to do individual lookups for each song


Support Message now can be sent with Support Files

Now when you send us your support files you can send a support message at the same time. This makes the reason for sending the support files clear and avoids you having to send a separate email message.

Help can now be hidden

In Remote mode help text was displayed on screen making it easy to see what all the options do. But this does take up screen space so we have now added the option to toggle Help on/off with the Show Help/Hide Help button

Report Creation has own Progress Bar

Previously no progress bar was shown for the Report Creation that occurs after the task has completed. However the report creation itself can take some time if you have been working with a large collection. So now Report Creation has its own progress bar that increases as the report is created making it clearer when the task is going to complete. The Report Creation progress bar uses a 1-100 percentage scale.

User Log is now more useful

The user log, songkong_user0-0.log has now been improved. Previously user log only contained errors and a summary after a task had completed. We now add a summary of song groups matched as they are matched. 

10/09/2018 18.18.12:BST:SEVERE: G1164:Matched to MB/AcoustId:Ave Maria:9 of 12 to Ave Maria:cf1d4e8f-ae69-46cb-9c5c-c941951ded58 by Vyatcheslav Kagan-Paley
10/09/2018 18.18.12:BST:SEVERE: G1164:Linked to Discogs:Ave Maria:9 of 12 to Ave Maria:7135466 by Vyatcheslav Kagan-Paley
10/09/2018 18.18.13:BST:SEVERE: G8883:Matched to MB/AlbunackAcoustId:Picture This:12 of 12 to Picture This:423f245e-1c75-4948-9f48-cc4c5c8159f4 by Wet Wet Wet
10/09/2018 18.18.13:BST:SEVERE: G8883:Linked to Discogs:Picture This:12 of 12 to Picture This:6859962 by Wet Wet Wet

Each line is preceded by date, and then a Group Id of the form Gnnnn. The Group Id is simply a way for us to identify a group of songs (usually a folder). Then we have a message explaining how matched to MusicBrainz or Discogs

Whilst the user log is primarily a debugging aid for use by JThink you may find this additional information useful.

Many Bugs Fixed

We have been hunting down some of the more obscure bugs in a sustained effort to try and get bugs down to zero.In this release there are over twenty bug fixes

The full list of improvements and fixes can be found on the News Page

Automatic adding of ISRCs to Jaikoz and SongKong

Automatic adding of ISRCs to Jaikoz and SongKong

We are pleased to announce that the Albunack database now supports ISRC's (International Standard Recording Code). ISRC enables recordings to be uniquely and permanently identified.

We already had support for ISRC in Jaikoz and SongKong but the data was not in the database. Now it has been added you'll see your existing versions of Jaikoz and SongKong can now add the ISRC for many of your songs.

Of  19 million MusicBrainz recordings in Albunack we have ISRC's for 8 million, that is coverage of 42%

SongKong 5.8 - Bug Fix release

SongKong 5.8 Released Today

We uncovered a handful of issues with the SongKong 5.7 release, these have all been fixed with this release.

One of these issues was that Edit Metadata failed to work in regular Desktop mode. This was due to the move from Java 8 to Java 10 in the last release, this exposed a bug that wasn't picked up because I had retested Edit Metadata before the move to Java 10.

We also at last fixed an annoying issue whereby SongKong would sometimes report it was cancelled because of an Unreported Error. Because the error was unreported it was very difficult to track down what the underlying problem was, but eventually we got there and it has now been resolved. 

Full list of fixes can be found at http://www.jthink.net/songkong/news.jsp

SongKong 5.7: Super Speedy Release

We are please to announce the latest version of SongKong today. There are many improvements in this release but we have concentrated on improved performance and further improvements to the Web Remote User Interface.


Albunack Disc Ids 

We have added a new way of identifying your songs. If you already have folders representing a whole album (or disc of a multidisc album) and the filename/metadata can correctly identify the order of the tracks then we create an AlbunackDiscId based upon the order of the tracks and the length of each track, we can then compare that with albums in the MusicBrainz database.

This is similar to the freedb lookup but has three important difference:

1. You don't need the CD, it may never even have been available as a CD. The Freedb algorithm is based on CD disc offsets, AlbunackDiscId is based on track lengths. Both calculate track length to the nearest second.

2. We are looking for matches in Albunack database not Freedb. so once a match is found SongKong can add high quality MusicBrainz metadata not poor quality freedb data.

3. It is more accurate, freedb can return matches for CD's where total album length and number of tracks is the same but individual track lengths are different. Albunack Disc Ids only match if all the track lengths match as well.

This method allows us to find matches that we could not match before, since there are many releases in MusicBrainz that are not yet linked to AcoustIds.

In this first release  we only use against MusicBrainz releases since these have more accurate track length data
But it also improves performance significantly as we no longer need to generate Acoustid fngerprints for all songs. However we do sometimes generate and check some acoustids for the matched release as an extra verification check.

Acoustic Fingerprinting

Previously we always fingerprinted every song and then did a lookup to find the AcoustId of each song. This only has to be done once for any song however the fingerprint generated is very cpu intensive and on slow machines can contribute significantly to total tagging time. Even on fast machines if the files are on the network  then fingerprinting will be significantly slower. So now instead of automatically fingerprinting songs at the start they are only fingerprinted as required during the Match to MusicBrainz stage.

For this reason the Acoustid Fingerprinting option on the Match tab has been modified. No longer does it default to true and mean that it must be enabled for fingerprinting to be performed. It now defaults to false and should only be set to true if you want to force SongKong to create fingerprint and get Acoustids even when a successful match has already been achieved.

Other Performance Improvements

We spent some time evaluating SongKong  performance using a profiler and found some unexpected bottlenecks that we have fixed.

Although we store AcousticBrainz data in Albunack we only have some of it because unfortunately they have not released a database dump for some time.  This if we don't find AcousticBrainz data in Albunack we then lookup in AcousticBrainz. 

But a lookup is required per track and if you rerun FixSongs on previously matched tracks that do not have AcousticBrainz data it will recheck. So now we are also now caching AcousticBrainz lookups so we dont retry failed lookups. If you really want to retry in case AcousticBrainz data has been added for the tracks then just run Empty Database, (ensuring you do not need to revert any changes first)

With the introduction of Albunack Discs Ids and all the other  performance improvements you should typically see that SongKong performs 3 times faster then the previous release.

Remote User Interface

We have made further improvements to the web browser user interface.

You can now add, edit and delete rename masks and javascript functions to use in these masks, just like you can in the desktop interface.

We have moved tasks and links from the footer to a fixed navbar so that they are always visible even on vertically scrolling pages.

And the footer now just contains links to the SongKong site and social media accounts, these will all open in a new tab.

The Edit metadata task tables now automatically size for content.

Hi Res Screen support

SongKong has  now been updated to Java 10, and this now provides full support for hi density resolution displays. This means screens whereby the ratio between pixels and resolution is not 1:1, the additional pixels are used to provide a sharper display.

There are many more improvements and fixes in this release and you can find the full list at http://www.jthink.net/songkong/news.jsp

Jthink has been Bootstrapped

We are pleased to announce we have now updated the suite of Jthink websites to use Bootstrap

You may not have heard of Bootstrap but you will certainly come across websites that use it. It was originally by Twitter then open-sourced and is probably the most popular CSS framework at the moment. 

Key reasons why we have moved to use Bootstrap are threefold: 
  1. Bootstrap enhances the default look of html components such as buttons.
  2. Bootstrap adds easy to use complex components such as navbars and footers
  3. Bootstrap makes it easier for to create responsive websites, i.e one that adapt to their screen size and input devices.
Each sub site uses the same font and style, but we have colour coded the navbar to easily distinguish where you are.
