Add music to Apple Watch
When you add music to your Apple Watch, you can listen to it wherever you go, even when you don’t have your iPhone with you.
You can add specific playlists and albums to your Apple Watch using the Apple Watch app on your iPhone. If you’re an Apple Music subscriber, you can also add music with the Music app 
directly on your Apple Watch.
Note: You don’t have to choose specific music to add to your Apple Watch if you’re an Apple Music subscriber. Music you’ve recently listened to is added automatically. (If you haven’t listened to anything, music recommended by Apple Music is added.)
Add music using your iPhone

Tap My Watch, then tap Music.
Below Playlists & Albums, tap Add Music.

Music is added when Apple Watch is connected to power and placed near your iPhone.
Tip: Use the Music app on your iPhone to create playlists specifically for music you want to listen to on your Apple Watch—music that motivates you during a workout, for example. See the Apple Support article How to make a playlist in the Apple Music app.
