Troubleshooting problem with file numbering display

[simoncn]

You should stay with ID3v2.4. Earlier versions such as ID3v2.3 have significant limitations. For example, there is limited and inconsistent support for having multiple values for the same tag name.

Regarding the problem with the playlist order for this specific album, a first step would be to check the DISCNUMBER and TRACKNUMBER tags for all 58 files. For files on the first disc, DISCNUMBER should be 1 and TRACKNUMBER should be 1 to 29. For files on the second disc, DISCNUMBER should be 2 and TRACKNUMBER should be 30 to 58 (or 1 to 29).
