If you have AirPods, you can control music and volume, handsfree.
If your hands are busy or you just don’t want to fish your phone out and you have AirPods in, use Siri.
“Hey Siri, play Surrender by Jeremy Glenn”
Siri will search Apple Music for tracks and Artists. If you specify “My Library” or “Playlist” it will restrict the search to your collection of music.
“Hey Siri, play Jeremy Glenn from my Library”
You can control playback as well.
“Hey Siri, pause”
“Hey Siri, play”
“Hey Siri, next track”
You can even adjust the volume level by specifying a number between 0 and 100.
