All the music players are visible in the bottom left hand corner, 
they're all black now due to the change that YouTube made.
BE SURE TO REMOVE THE CURRENT MUSIC PLAYER CODE (IF YOU HAVE ONE} BEFORE YOU ADD ANOTHER!
AND YOU CAN ONLY HAVE ONE MUSIC PLAYER AT A TIME OR THEY WILL ALL PLAY AT THE SAME TIME 
AND YOU WON'T BE ABLE TO HEAR ANY OF THEM.
