Can I set 1 (music) app to the Music Controller on the AOD / Lock Screen?

[daherlihy]

Is there anyway I can set the device up so that only 1 app is applicable to the Music Controller, rather than the last music or video app which was playing a song or video?

I want to have Google Play Music always available on the Music Controller on AOD and Lock Screen.

However when I play a video in the YouTube app for instance, and then go back to the Music Controller on the AOD and lock screen, it has the controls ready to play the YouTube video ... meaning I have to unlock the phone, open Google Play Music and play a song for the app to be restored back to the Music Controller - very inconvenient.
