Is there an automatic way to enter the 'of' tag?
If you have lots of full albums, then copying "album track count" value to "track count" field could help the process. The problem is "album track count" field is not available for boroda74's plugin. You might want to ask him to add the field.
- First, create an auto-playlist with the rule of "Disc Count" "is less than" "2".
- Select all files in the playlist, go to Tools> Tagging Tools> copy tag, and copy "album track count" value to "track count" field.
