Last Song Syndrome

              What is  a "Last Song Syndrome"? This is the situation where you keep on singing a certain song again and again, that is stuck in your head. Its not deadly but its contagious. Contagious because, when your beside a person who is encountering  a "Last Song Syndrome" you can't help yourself singing in your mind most especially when you know the song. When you have the LLS you can't help yourself singing the same song in one day. Most of the time you sing the songs that you like, how you feel or perhaps a song that describes your day. Sometimes when you hear a certain song in the radio it registers in your head and you keep on singing the song over and over again, even when the song is  already over. From time to time the melody of the song is constantly playing in your head. You tend to sing the song even though you don't know the lyrics, or you just hum. So do you have a LLS? :)
