Problem with multidisc album with disc subtitle

[paultaylor]

Okay so forgetting about the IDv23 issue it does indeed work for ID3v24 after all for this release because I have DISCSUBTITLE set to the disc name. However my problem is that it doesnt work for multi-disc releases that don't have disc subtitles because I only set the discsubtitle when the disc has a title rather than just when it is part of as multidisc. I can get it to work for these releases by enabling 'Always add Disc no to release titles' for multidisc albums, but then this breaks it for album with subtitles.

I can maybe change something in Songkong but Im not sure I want to write 'Disc 1' to DISCSUBTITLE as I dont think that is actually a disc subtitle.
