I was walking up town at lunch today, listening to music in my own little world. I passed another person who was likewise listening to music. I wondered what were the chances that we'd be listening to the same song.
Then I thought of this: If I had to walk the earth, listening to music, and I had to stop each person I met who was also listening to music, and ask them what they were listening to... If I had to do that until I found somebody who was listening to the same song at the same time I was...(follow that so far?) would I have a greater chance of success if I continually listened to the same song, over and over, until I found somebody who was also listening to that same song... or would it be better for me to randomly listen to songs, hoping to meet somebody who also randomly was listening to the same song at the same time?
I need to know.
