UPDATED: Increment Number Tags v4.3
This script will incrementally number your choice of the Track Number, Movement Number, Episode Number, Episode ID tags, and track Name prefix of the selected tracks. Additionally, a Track Count, Disc Number/Count and/or Movement Count can be applied to each track, Episode ID can be configured with additional text incorporating the number, and zero-padding up to five digits can be applied. (The selected tracks must be sorted by ascending Play Order for accurate results.)
