Music stops when timer ends and does not restart

Hello dwttulsa,

Thank you for reaching out in Apple Support Communities. For the music to unexpectedly stop from a workout, are you noticing this behavior with any song that's playing? If you haven't tried yet, we recommend to restart both the Apple Watch and the paired iPhone. This is a step that can help resolve unexpected behavior. Here's how to restart each device:

2. Press and hold the side button until you see the power button  in the upper-right corner of the display.
3. Tap the power button.
4. Drag the Power Off slider.
5. After your watch turns off, press and hold the side button again until you see the Apple logo.
