I believe in os 2, you could just swipe up and have a music control shortcut. To control music on my iPhone, is there any quick way without having to go into the music app on the watch? Thanks.
There's a Now Playing tab on the dock always available when listening to audio, so a click and a tap for you to get volume and track controls. Though you could build a watchface for entertainment/music containing the Music.app as a complication.
