If you're working out or running, or just walking to your next meeting, you may want to listen to music. The Apple Watch gives you two ways to do this: by controlling music on your iPhone, or by playing music directly from your wrist, streamed to Bluetooth headphones. You can play music from your iPhone, or from Apple Music if you're a subscriber. And you can even control your music hands-free. Here's how to play music on your Apple Watch.
Control your phone
The Now Playing glance lets you control what's playing on your iPhone, or your Apple Watch. Tap the name of the item to see its album artwork. This glance controls any app that plays audio on your iPhone: Music, Podcasts, iBooks (for audiobooks), and more.
If you want to listen to music on your iPhone, you can control it from your Apple Watch. The Now Playing glance acts as a controller. Swipe up, then swipe sideways until you see it. (If you don't see it, add it to your Apple Watch in the Watch app on your iPhone, in the Glances settings.)
If you tap the time at the top left of the Now Playing glance, your Apple Watch moves to its top-level Music controller. You can see Now Playing, Quick Play, Beats 1, My Music, and, if you scroll down, Playlists.
Tap My Music to view all the music on your iPhone; you can tap a menu to view by Songs, Albums, or Artists. Tap an item to start playing it.
A quicker way to launch music—and a better one if you're running, for example, and can't tap your watch's tiny display—is to use Siri. If you have "Hey Siri" enabled (Settings > General > Hey Siri, on the Apple Watch), just hold your watch up and say "Hey Siri, play Grateful Dead." Or, press the digital crown to activate Siri, and give a command. Siri searches your iPhone—this can take a few seconds—and starts playing the artist, album, song, or playlist you requested.
One problem with Siri is that it searches both your iPhone and Apple Music, even if Apple Music is not visible on the iPhone. So you may start playing music that's not on your device, and use data without any warning.
Also, Siri's recognition is never perfect, and if you request something non-standard, Siri may not find it, or may find something very different. For example, I asked Siri to "Play John Foxx Metamatic," and Siri replied, after a few seconds, "I couldn't find 'John Fox meant to magic' on Apple Music or in your library" When I asked Siri to play John Foxx, it started playing John Fox, who, it turns out, is a stand-up comedian, not the musician.
