For macOS 10.10 and later only Quickly compares the contents of any two playlists and displays the tracks that are common to both or the tracks in one playlist not contained by the other. Has tools to copy or move tracks from one playlist to another or delete common tracks from one or the other playlist. Can optionally create a text file report of these comparisons.
Free to try in Demo Mode: While in Demo Mode, several features will be disabled. An in-app purchase of a registration code will unlock the disabled features.
To purchase a registration code, download and launch the app. Click "Register..." in its File menu and follow the prompts to purchase a code for $1.99. When your payment is processed, you will be emailed a registration code that will unlock the Demo Mode restrictions.
Find out which tracks are common to both or exclusive to each of two drag-and-dropped playlists.
