Apple Music stops playing when I add a song to my library on Mac

Hey there, moizsaeed!

Thanks for visiting the Apple Support Communities. I understand that when listening to Apple Music, playback will stop if you add a song to your library. I'm happy to help!

There could be several things going on to cause this to happen. To help us isolate and troubleshoot, I recommend trying the following steps. Perform them in order, testing between each to see if the problem continues:

1. Quit any open apps on your Mac: Quit apps on Mac - Apple Support then restart it: How to turn your Mac on or off - Apple Support.
2. Check for and install any available updates for macOS (which should also update the Music app if there is an update for it): How to update the software on your Mac - Apple Support.
3. See if the issue continues in safe mode: How to use safe mode on your Mac.
4. See if the issue continues in a new, test user account: How to test an issue in another user account on your Mac - Apple Support.
5. If you have access to another network, see if it happens there as well: How to connect to the Internet with your Mac - Apple Support.
6. If you have access to another device (like another computer or an iOS device), see if the issue occurs there, as well: Add and download music from Apple Music or buy music from the iTunes Store - Apple Support.

Don't hesitate to respond back if you still need assistance.

Happy listening!
