From what I understand, getting a song stuck in your head is caused by a glitch in the auditory cortex. The suggestion by the researcher, to get it unstuck, was to do some math. Unfortunately, sometimes I get it bad and nothing really works.. like one song constantly for a week or more. By the end, I feel like I’m being tortured and never want to hear the song again!
You made me think of one morning recently, where I opened my eyes, stared off into space for a few seconds to wake up, and then “IT’S MY LIFE, IT’S NOW OR NEVER” (Bon Jovi) went through my head. I am not a Bon Jovi fan and couldn’t even tell you how long it’s been since I heard one of his songs. It was a message from my subconscious, though. And totally random.
