Media Player Widget that goes away when media player app is closed?

Hello, so was wondering if anyone knows of a media player or a media player widget app where it appears on your home screen when the music player app is open but then goes away on its own when the app is closed? I don't want the widget to always be there and manually removing it every time is just a hassle...

Thanks!

When I use Pi Music Player and it is minimized, a controller for the app will appear in my notification bar. I can press an X to close it from there and it will disappear. No need for a widget. Amazon Music does the same thing.
