# Soundiiz

> Soundiiz copies supported playlist and music-library metadata between music services. It also provides one-way playlist Syncs and Smartlinks. Other workflows include imports and exports. Developer APIs are available.

Soundiiz does not host, stream, download, or sell music. A transfer copies metadata and never deletes or changes the source. Smartlinks support public sharing of a playlist or release.

A service being listed does not mean that every direction or item type is available. For a transfer, an item type is available only when the source can read it and the destination can write it. Supported item types: playlist, track, album, artist. Sync is one-way, covers playlists only, and requires connectable source and destination accounts. Plan limits, account eligibility, region, catalog matching, and current music-service availability can still affect a run.
