Spotify glitched and duped every playlist multiple times. Removing manually would have been a Herculean task. Googled "removed duplicates from Spotify playlist." Dedup came up. It worked perfectly. Thank you.

This is exactly what I needed. So glad there are others out there who believe a good playlist should not only be curated but be treated like a database and regularly maintained.

Frequently asked questions

What does this web application do?

Spotify Dedup helps you clean up your music libraries on Spotify by identifying and deleting duplicate songs across playlists and liked songs.

How does it find duplicates?

Dedup finds duplicates based on id, title, artist, and duration similarity. You can customize the matching criteria in 'Advanced Options' to use stricter or fuzzier matching rules.

How is Dedup better than Spotify's built-in duplicate detection?

Spotify's applications only warn about duplicates when adding a song to a playlit or liked songs with the exact same song identifier. However, the same song can have multiple identifiers on Spotify that both in the same release or in several ones. Dedup detects duplicates based on title, artist, and duration similarity.

When duplicates are found, which songs are removed?

By default, Dedup keeps the oldest song (the first one added) in a group of duplicates and removing the rest. You can change this behavior in 'Advanced Options' to keep the newest song instead.

Is my data safe with this web application?

Yes, this web application does not store any user data on its servers. It only requests the minimum set of permissions necessary to process your library.

What permissions does this web application require?

This web application uses Spotify's authentication service to access your liked songs and playlists in your library.

How has this tool been tested?

This tool has been battle-tested by thousands of users who have used it to identify duplicates in millions of playlists since 2014.

Can this tool delete duplicates across multiple playlists?

This tool can identify and delete duplicates on all playlists in a library, but doesn't detect duplicates of a song across multiple playlists.

How can I revoke the permissions granted to this web application?

You can revoke the permissions granted to this web application at any time on your Spotify account, under the 'Apps' section.

Does this tool work with other music streaming services?

No, this tool only works with Spotify through Spotify's Web API.
