This n8n workflow automates the synchronization of a YouTube playlist with a Spotify playlist, ensuring only unique tracks are added. It begins with a manual trigger, then retrieves tracks from both playlists. The workflow extracts Spotify track IDs and searches for corresponding tracks on Spotify to confirm their existence. It compares existing Spotify tracks with new YouTube tracks, and finally adds only those tracks that are not already in the playlist. This automation is ideal for music enthusiasts who want to keep their Spotify playlist updated with new content from YouTube, avoiding duplicates and manual effort.
