Music Player in Lock Screen of Samsung Galaxy S4

I know that lock screen widgets are only available if you have a Swipe lock screen method in your phone. But some of the widgets are can also be used even though you have a more secured lock screen method like Pin and Password. One of the available widgets that can be used in secured mode is the Music Player. Many people are asking on how to show/hide the Music Player on lock screen of Samsung Galaxy S4. At first, I can't figure it out on how to purposely show/hide the music player so I made several experiments. Today I want to share my findings.
