Audiobook out of sequence

Here are a few suggestions to get you on the road to a working solution.

  1. Try using mp3tag software (shareware) to edit the Filenames and ID3 tags in your audiobook files.
  2. Try using Album names (book titles) and FIlenames (chapter titles) that have unique sorting information within the first 12-16 characters.
  3. Try using track numbers from 01-99. Three digit track numbers will not sort correctly.
  4. For tracks above 99, you can try creating a “Part B” of a Book and re-start the track counting from 01.

Example version of this tagging scheme.
Album Names: Abcdef-CD01, Abcdef-CD02, Abcdef-CD03, etc [no higher than CD99 for one book]
  Titles (Chapter Titles): Chapt 01, Chapt 02, Chapt 03, etc [no higher than Chapt 99 for each CD]
    2-digit track numbers that match the Chapt numbers for each CD. Start renumbering at 01 for each CD.
