# MPMediaItemPropertyAlbumArtistPersistentID

The persistent identifier for an album artist.

```
let MPMediaItemPropertyAlbumArtistPersistentID: String
```

## Discussion

This value is an <doc://com.apple.documentation/documentation/Foundation/NSNumber> object that contains a `uint64_t` (unsigned long long). The value of the `MPMediaItemPropertyAlbumArtistPersistentID` identifier persists across application launches and across syncs that do not change the sync status of the media item. The value is not guaranteed to persist across a sync/unsync/sync cycle.

Can be used to build a media property predicate as described in [`MPMediaPropertyPredicate`](/documentation/MediaPlayer/MPMediaPropertyPredicate).
