Default Music app deleted when I updated my lollipop 5.1 system

[AC Question]

Yesterday afternoon I update my lollipop 5.1 system. I waited and after the successful update, my phone restarted. I then tried to open the music application but after touching the icon it disappeared. I searched for it at the home of my phone but it was not there! I opened the music play (Google) and the music plays but I don't really like this application. Please let me know if you have any solution to my problem.

I think the first and easiest thing to try is to do a "factory data reset" ... Haven't you already?
