media_library_show_audio_playlist │ хук-фильтр │ WP 4.7.4

Allows showing or hiding the "Create Audio Playlist" button in the media library.

By default, the "Create Audio Playlist" button will always be shown in the media library. If this filter returns null, a query will be run to determine whether the media library contains any audio items. This was the default behavior prior to version 4.8.0, but this query is expensive for large media libraries.
