This script will change the extension/file type of the files of the selected AAC tracks to M4B which makes them natively bookmarkable (that is, the track will resume playing wherever you left off the last time you played it). Deletes and re-adds each file so its track will appear in the Audiobooks/Books library. Ratings, play count, last played date, skip count, and skipped date are preserved.
