Do You Hear What I Hear?

A little girl was lying over two seats when I got on the T today. Her father lifted her up to make room for a huge crowd of people that had just boarded.

"Where is that music coming from?" she asked him.

"Someone's headphones," he answered. "The train doesn't have it's own soundtrack."

"Yes it does," I thought. Just ask Pauline. (Start with 3:15-5:25.)
