iCloud Music Library can't be enabled
Solution 1:
Keep trying. After toggling the setting to enable it a dozen times over twenty minutes, it finally worked. This appears to have been a temporary problem associated with the launch.
Solution 2:
From iMore
- Launch Settings from the Home screen.
- Tap Music (note, the icon has changed colors).
- Toggle iCloud Music Library to On.
- Choose if you want to Replace or Merge your library. (I ultimately chose Merge when it worked).
- If you get the error again, dismiss it.
- Repeat steps 3-4 until it works.
