If you have a subscription to Apple Music, all of the functions of Apple Music are available to you. You have access to the entire catalogue, all Apple Music playlists (including playlists that you make), all radio stations, episodes of Beats 1 and your own personal mixes. Siri can search by artist or album and manage what is being played and give you information about the music that is being played. Siri can play music from your music library without an Apple Music subscription, including your iTunes purchases and iTunes Match songs.
