Soundiiz
Transfer and synchronize playlists, albums, artists, and tracks across music streaming services.
Soundiiz lets you transfer playlists, albums, artists and tracks between supported music streaming platforms and keep selected playlists synchronized over time. Features listed include one-time transfers, ongoing synchronization, Smartlinks for promotion, and Playlist AI for generating playlists from text, moods, genres or years. The site supports dozens of services (46 available services), offers a free plan for eligible one-by-one transfers and a paid monthly plan for batch and advanced transfers; subscriptions can be cancelled in user settings and paid features remain until the billing period ends. Soundiiz connects via each music service's authorization methods (access can be revoked), is operated in France and follows GDPR. Transfer reports list tracks that are unavailable or cannot be matched. Transfers copy matched playlists and supported favorites to the destination without deleting or modifying the source.
