Stuck in my head

How does that happen, anyway?  Is there some sort of formula that guarantees a song will be a winner? when i grow up... I like music, i really do, but sometimes I want my head to be quiet.  I want to turn the music off ...i wanna be famous... and i want silence.  i just want to think and wonder, I dont want stuff, noise,...i wanna be a star... bouncing around.  where is the mute button?  If the brain is such an awesome, complex thing, there should at least be a mute button.
