Playlist Structure

The playlist structure defines the outer container that holds all tracks and playlist-level information.

Core Playlist Fields

Every playlist contains these essential elements that describe the collection as a whole:

The Tracks Array

The tracks field contains an array of track objects. Each entry in this array represents one piece of music that can be played. This is where the actual content lives - the playlist structure just organizes and describes the collection.
