Using onPause() is not a good solution because when you open another activity the onPause() of previous activity will be called while your app is visible!

this is what you should do: Create an application class and override onTrimMemory() method:

public class App extends Application {

@Override
public void onTrimMemory(int level) {
    super.onTrimMemory(level);
    if (level == ComponentCallbacks2.TRIM_MEMORY_UI_HIDDEN) { // Works for Activity
        //implement your code for stopping music
    }
    else if (level == ComponentCallbacks2.TRIM_MEMORY_COMPLETE) { // Works for FragmentActivty
         //implement your code for stopping music
    }
}
}

do not forget to define this class in Manifest.xml:

        android:name=".App" //add this line in application tag of Manifest file

You can use the onPause()-Method of the Activity-Class to stop the background-music. When the app gets resumed you have start it again with onResume().

See: http://developer.android.com/reference/android/app/Activity.html#onPause%28%29

The onPause() method that you can override in your activity will be called when the application is removed from the user's view.

Place whatever code you need to stop the music within that method, and you can be sure it will be called when the user presses 'back' or 'home'.

See here for the activity lifecycle:
