UPDATED: Scan For Double Entries v3.1
For macOS 10.15 and later only. This applet will scan your Music library for pairs of track entries that–very strangely–point to the same file and then copy those tracks to a discrete playlist for further examination; presumably you’ll want to remove one of the faux pair tracks without Trashing the single associated file.
More about this issue is here.

Latest version:
- Accommodations for macOS 11 Big Sur
- Performance, UI and security enhancements
