Yes I've seen it a couple of times Happness is a warm gun...Be happy don't worry...love the music that's being played on your systems....just take your head phones off...like the people who walk or jog or run....and have ear pieces or head phones on....just walk or run....with out ,music or stories or books,being read to you....listen to the sounds of the world you walking at....let your ears rest....be natural no sounds...
