UPDATED: File Renamer v5.4
This applet 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.
Works optimally for “in place” option with Music app’s “Keep Media folder organized” un-checked.

Latest version:
- UI and layout adjustments
- Larger pattern entry field
- Zero-pads all single-digit track and disc numbers and counts
- Better validation of pattern
- Fixed further regression issues
- Maintenance
