## What it is
Spotify Dedup is an open-source web application that scans a user's Spotify playlists and liked songs to find and remove duplicate tracks via the Spotify Web API. It preserves playlist metadata like creation date and subscribers, and offers advanced deduplication options with user review before deletion.

## Use cases
- remove duplicate songs from my spotify playlists
- clean up duplicated liked songs in my spotify library
- dedupe a huge playlist with thousands of tracks
- find repeated tracks across my spotify account
- alternative to spotify's built-in duplicate remover
- bulk remove duplicates without recreating playlists

## When to choose
- you want a free, open-source tool to clean duplicates from Spotify playlists and liked songs
- you need to process very large playlists (thousands of tracks) that other tools struggle with
- you want to keep playlist metadata like creation date and followers while deduplicating
- you want to review duplicates before anything is deleted

## When to avoid
- you need deduplication for other music services like Apple Music or YouTube Music
- you want an offline tool that works without connecting to Spotify's API
- you need to deduplicate by audio fingerprint rather than Spotify URI matching
