Multi Disc Releases: Disc Subtitle field
The Disc No field is very useful in multiple disc releases, for example to distinguish between the first track on disc 1 and the first track on disc 2, we can also add the discno to the Disc SubTitle field for all MultiDisc releases with the Always add Disc Title or Disc No to the Disc Subtitle option . Multi-disc releases sometimes give an actual name to each disc and this can be added to the release title by setting the option to Add Disc Subtitle if Disc has Title .Or you can elect to do nothing special for multi-disc release by setting the option to Never add Disc Subtitle .
