UPDATED: File Renamer v5.0
For macOS 11 and later only. This script will rename the files of the selected tracks (or the files of the tracks in the selected playlist) using a substitution pattern that you formulate from the tracks' tag data. Optionally, export a copy of the files to a chosen location and rename the files in that location.
Latest version:
- Updated to support macOS 12 Monterey
