Nice! The results aren't surprising, given the variables encountered in commuting. I suspect that he'd have seen similarly random results if he'd isolated any of a range of similar variables---which songs were repeating in an irritating loop in his head on which days, etc. In fairness, similar trials were conducted on a somewhat broader scale in professional racing in the 1990s, with different results.
