Picture being at a barbecue. You want music playing but you also want the freedom to walk around.

Instead of a user having to keep her phone on her person, she can leave it plugged into a speaker or charger and use her Apple Watch to control it. There are two steps to integrating your iPhone app with Apple Watch’s remote media capabilities: providing information about what’s currently playing and responding to remote-control events (like the pause or fast-forward buttons).
