We all have a lot of music, and it often happens that we have songs that are not assigned to any playlist. Some DJ programs (such as Engine DJ or rekordbox) only transfer songs to the USB stick if they are assigned to a playlist. It would be very helpful to have a feature that displays all the songs that are not yet in any playlist.
You can do this with the Playlist Occurrence utility: Playlist Occurrence | Lexicon - DJ Library Management
Oh wow, thank you for the quick response, and I apologize for being so blind
