You are making me laugh. I love that commercial and so does my youngest son who dances right along with the man.
I didn't mean to go off topic here as I know how much the racing thoughts are bothering you. I think it will be a good idea to bring it up with your therapist to work through it if it is bothering you. I did read somewhere one time that when you pick up theme songs/jingles, etc and they stay in your mind, it is just your creative juices flowing and you are using one side of your brain more than the other (I think it's your left side which is the creative side?).
Now I have that song in my mind too
