Frustrated trying to manage duplicate music tracks on your Mac?
Of course you are!
The Show Duplicates feature is helpful but you still have to examine every single track and somehow decide whether you want to keep or delete the duplicates it might find.
Now there's Dupin. Your duplicate tracks manager. For macOS 10.15 and later only. (Dupin v2.14.1 for pre-macOS 10.15 is still available.)

What reviewers say (about the older iTunes version):
- "Dupin [does] a much better job than iTunes' Show Duplicate Items command of finding and zapping duplicate files, letting you easily tame overflowing libraries."
- Jonathan Seff, Executive Editor, Macworld, "5 Essential Tools That Every iTunes User Should Have" - "Dupin comes in so handy, and for $15 it's a small investment for your sanity."
- Dave Taylor, Mac Author, Ask Dave Taylor - "Dupin does an excellent job finding all those pesky duplicates and removing them from your iTunes library."
- Roberto Baldwin, Mac|Life - "The app performs well and comes with an accessible interface and excellent functionality. If you have a large iTunes library, you'll love it."
- Chris Page, Editor CNET's Download.com - "If, like me, your iTunes library is an unholy mess, I'd suggest you give it a spin."
