Glad it worked, can it be something with different tagging formats? I do not know. Hope someone here could explain this.

All the tracks seem to be there, only with some wrong track numbers, some wrong track names and dispaying in the wrong order.

All that data comes from the embedded tags. File names and folder names are not used at all.
First step is to check your tags, and you should find they match what you are seeing in Kodi.

As you say, it was the tags.  The tags on the files I started with were messed up and I wasn't able to fix them.  I eventually bought another copy of the CD's and ripped that.  The tags from that rip still had problems but I was able to use Bliss to fix them.  The set now displays and plays correctly.

I eventually bought another copy of the CD's and ripped that.

The tags are not in the CD's. The tags are added to the music files by the ripping software. But the tags added at this point are very basic.

You should then grab those ripped music files and run them through MusicBrainz Picard to add the full compliment of tags that Kodi uses.

Use Picard (or similar tagging software) to add disc titles to each disc

Please do not stuck to a song-per-file scheme. There could be dozens of reasons why one wants to keep his/her music collection by file+cue scheme. It is a very bad idea to ruine one's habbits. And, by the way, CD ripping/burning software like CUETools or EAC successfully read REM DISCSUBTITLE "" tag from the cuesheet. Maybe keep file+cue support as a foolproof method.
 

Add 'boxset' to the Musicbrainz_album_type tag. Thats the one where it says 'album', compilation', 'single'

Even this feature could be achieved with cuesheets by REMing non-standard tag. But if it is impossible to achieve with the KODI's then maybe you will allow to combine the tags from the cuesheet file with the tags from the single album file into the KODI's music database.

Kodi will still navigate to discs -> tracks if there is more than 1 disc in an album

Will it still show the discs' names or just Disc 1, Disc 2 and so on? Hope it will show their names.

By the way, there is a Singles node available by default in Music. Frankly when I saw this node for the first time I thought it could allow to separtate music albums from the music singles, but it collects the songs without the album title instead. Will it be possible to list music albums and music singles separately, keeping in mind that the music singles always have their own album title?

To all the developers and contributors - many thanks for making this feature possible! Your work is very much appreciated!

I have a quick question related to the first item in @garfield post above - is managing Box-sets feature works for single flac file + cue sheet structure? I have a lot of box-sets ripped in this way. Splitting each CD by individual tracks is a pain...

I have tried a few approaches (amending cue file by adding REM DISCSUBTITLE, setting 'boxset' to Musicbrainz_album_type tag or adding relevant DISCSUBTITLE tag to each single flac file), but so far had no luck. 

Could anyone please help?

Thanks!

[black_eagle]

No, sorry.  Boxsets are not supported via cuesheets, nor will they ever be. Splitting your FLAC files might be a pain but you will only have to do it once.  The cuesheet support we do have is legacy and I believe follows the original spec from ~2000 but there is absolutely no need to use them these days.  Kodi is perfectly capable of playing a gapless album for instance from individual tracks.

[Harbour]

Hi @black_eagle,

Thank you for your prompt response, really appreciate your help! 

It is a pity that boxset feature is not supported for cuesheets, as I've thought that ripping CDs this way is still popular... 

Anyway, I want to tag everything correctly in my library, and therefore am keen to make a change. However, before I start splitting single FLACs, could someone please tell me what advantage I will get by going this way (i.e. splitting each CD's FLAC and attributing proper 'boxset'/'subtitle' flag) as opposed to adding REM DISCNUMBER to a each of the cuesheet files in a set?

For example, consider J.J. Cale boxset 'Collected':

https://musicbrainz.org/release/874ac5ef...e2412c54a6

Here, three 3CDs don't have individual names (subtitles), only CD1/CD2/CD3. In my case I have a boxset root folder with an album.nfo file (contains review, label, MB tags, etc.) and an album art (folder.jpg). I also have three subfolders (namely CD1, CD2 and CD3) each containing flac, cuesheet and discart. Each cuesheet contains relevant REM DISCNUMBER (i.e. 1,2,3).

If my understanding is correct, converting this structure into a boxset by splitting each of the three FLACs into individual tracks' FLACs and adding relevant DISCSUBTITLE to each track (something like 'Disc 1', 'Disc 2', 'Disc 3') will not change appearance from what I already have. Is this correct?

It would've been a different story if each of the CDs had individual names. Then, yes, it would've changed appearance nicely. 

Is there anything else that I am missing here?

Many thanks.

If you add DISCSUBTITLE's to each track of a disc (Doesn't matter what you call them) and the album is not marked as a compilation, then Kodi should recognize it as a boxset when scanned in and flag it internally as such.  If for some reason that doesn't work you can set MUSICBRAINZ_ALBUMTYPE to "boxset" (or to contain that value along with others) and Kodi will honour the tag and construct a boxset (even without disc subtitles, it'll internally create "Disc 1", "Disc 2" etc).  This should work even if the album is marked as a compilation.

In mp3tag, the only available tag, or rather the one that comes closest is "MUSICBRAINZ_ALBUMTYPE". Is that identical to "MUSICBRAINSALBUMRELEASETYPE" or is it possible to just add such tag manually?

[DaveBlake]

In mp3tag, the only available tag, or rather the one that comes closest is "MUSICBRAINZ_ALBUMTYPE". Is that identical to "MUSICBRAINSALBUMRELEASETYPE" or is it possible to just add such tag manually?

The internal names of tags vary with tag format e.g. for FLAC it is RELEASETYPE, ID3 v2.4 (mp3) TXXX:MUSICBRAINZ ALBUM TYPE, and APE uses MUSICBRAINZ_ALBUMTYPE

These various internal names where defined by Musicbrainz, and in Picard (regardless of format type) they get the display label "release type". In Mp3tag I think both the ID3 tags and APE tag get the display label MUSICBRAINZ_ALBUMTYPE, but FLAC does not.

What Mp3tag is showing as MUSICBRAINZ_ALBUMTYPE is the tag you want to set to "boxset". BlackEagle unfortunately made a typo in the post you quoted.

You don't say what format file you are tagging and you don't need this, but yes you can add tags manually using Mp3tag (or you could use Picard instead).

Thanks much! In my case mostly m4a, but as discsubtitle was already set, seems the reason was just that "display as individual CDs" was not activated.

Revisiting the "boxset" feature which for me is one of the most exciting aspects in Kodi's music library presentation. Lately I have been converting my Bluray collection to digital resulting in multiple "discs" of different channel layouts. Typically, I get stereo, 5.1 and Atmos mixes from newer Blurays. Thanks to @HomerJau I have settled on .m4a as a good choice for Dolby Atmos container files. I can tag them fully in foobar2000 and Kodi reads enough of those to be able to add them to the music libarary. I have abandoned .mka for Dolby Atmos now as that is also used for audiobooks in Kodi and I would like to stay as compatible as possible between the two softwares.

Now, the reason for my post is that although I have split the different channel layouts to discs like so for example

1.1 - 1.10 Stereo mix
2.1 - 2.10 5.1 mix
3.1 - 3.10 Dolby Atmos mix

the boxset feature does not properly pick up on the .m4a files. Discs 1 and 2 in the above example are presented as a single release with split discs in boxset manner but the Dolby Atmos mix is not presented as a third disc but as a separate release with a single disc. Any idea why that is happening - maybe that format simply needs to be added to the boxset code?

[HomerJau]

Did you resolve your issue @HeresJohnny ?

To me I would check the MB ReleaseIDs and MB AlbumArtistID (they should be identical if you are using MBIDs), otherwise your Album and AlbumArtist tags should be identical. Then Kodi will group all the files into same Album and then by DiscSubtitle to group by ‘Discs’

In MMH you can load all your files into its ‘Tag & Rename’ tool grid and display all those columns or use the ‘Edit Selected Tags’ (after selecting all files in the grid: CTR+A) to check if all the values mentioned are identical. In the grid right-click on a column header and a pop up menu allows you to add the MB tag and DiscSubtitle columns to the grid view.

[HeresJohnny]

The issue remains. The tags are already as you say... I tagged with foobar2000 and Musicbrainz Picard and only added the "Boxset" tag. The only things I changed manually are the disc layout, so each mix would receive its own discnumber, and the discsubtitle to show what mix the respective disc has.

Edit: There is a possibility that I have used incorrect tags in .m4a for the musicbrainz tags. I have used the same tag format as for FLAC, will have to look into that.

[HeresJohnny]

Yup, it was a tagging issue on my side. I blame it on foobar2000... as much as I love that software, its musicbrainz tagging plugin isn't able to sense the codec/file format and will only use predefinded tags - in my case for FLAC files since they are my main use case. M4A on the other hand seems to use id3v2 style tags and once those were in place, sorting issues in Kodi were gone.

[black_eagle]

 I have abandoned .mka for Dolby Atmos now as that is also used for audiobooks in Kodi and I would like to stay as compatible as possible between the two softwares.

I have a branch that addresses that. I believe you commented on it on github but AFAICR, you mistook it to be the opposite way around.

To be entirely clear, mka will be an album (and support many tags). m4b will be an audiobook (this is apples standard for audiobooks). On that branch, this is auto-determined from the file extension. However, its also possible to force an audiobook by setting MUSICBRAINZ_RELEASETYPE to audiobook which allows for mp3 (or any other format) audiobooks. Possibly I might consider forcing an album too for mka files although that shouldn't be necessary.

There is a translation table at https://picard-docs.musicbrainz.org/down...g_Map.html if you want to use vorbis/ape/mp4 tags etc

mka album in that branch. This shows the file and some of the tags.



Album when scanned into Kodi (new branch).



Showing extra tags read from mka file.





Showing Audiobook info (m4b and mp3 etc) - Also shows a couple of podcasts but they could be separated out further if necessary.



If there is some interest I can trigger Windows / Android test builds for people to try out.
