Remove duplicates from playlists or migrate entire playlists into your Liked Songs — preserving order, skipping tracks you already have.
Detects duplicates by title and artist. Prefers album versions over singles. Creates a new cleaned playlist.
Add an entire playlist to your Liked Songs. Skips tracks you already liked. Adds in reverse order so "Recently Added" sort matches playlist order.
Tracks are added one-by-one. Automatically pauses and resumes on Spotify rate limits — no manual intervention needed.
Jobs checkpoint progress every 100 tracks. Interrupted jobs resume from where they left off — never restart from scratch.
