Dedupify

Find duplicate songs in your library

Dedupify scans your playlists and Liked Songs for the same track saved twice - even when the copies come from a single and an album, a remaster, or a re-release. Connect your Spotify account to begin.

You need a free Spotify developer app pointed at this page:

Go to developer.spotify.com/dashboard and create an app.
Under Redirect URIs add this exact value: loading...
Tick the Web API box and save.
In the app's User Management tab, add your own name and Spotify email (development mode requires it).
The app owner needs an active Spotify Premium subscription for the API to work.

Current Client ID: loading...

Choose what to scan

Pick the playlists and Liked Songs you want checked. Only playlists you own or collaborate on are shown, since those are the ones Dedupify can edit.
