Click on the application drawer button (brings up all apps)
Find music, click
Go to "now playing" and pause it, and exit out but pressing the home button
If your music icon is still seen in your notification bar, then after pausing it, hit "clear"
When you pull the bar down, hope that helps
I had a post about this. When you do hit pause, if you go into your settings from the home page, and look at the applications that are running, the music IS stopped. How hard would it have been to put a stop button in the program?
