Songs in My Head

[kokopelle]

I was thinking about the songs in my head.  This is a synchronicity of two recent things I read.  The first is that people wake up with song going through their head.  Guilty!  The second is that life should have a soundtrack.  Well, I have a song going through my head most all the time, so I guess I do have a soundtrack.  The mental soundtrack is often replaced by a recorded one when I listen to music at work or home. 

Is this normal?  I don't know.  I suspect it is, but if it is not, maybe I am "special" in the respect that I am very connected to music.  What do you think>
