# Playlist property keys

Keys that contain information about a playlist.

## Discussion

Use these keys with the [`canFilter(byProperty:)`](/documentation/MediaPlayer/MPMediaEntity/canFilter(byProperty:)) and [`value(forProperty:)`](/documentation/MediaPlayer/MPMediaEntity/value(forProperty:)) methods to obtain information about a playlist. You can use properties described as “filterable” to build media property predicates (see [`MPMediaPropertyPredicate`](/documentation/MediaPlayer/MPMediaPropertyPredicate)).
