If you were to make an educated guess, you could probably wager that the sort of music that a professional athlete listens to is something high-tempo, motivating and gets the blood pumping. Basically 'Eye of the Tiger' on repeat, in other words.

There are some interesting choices in there - such as Barnes's love of Kylie over the Rocky soundtrack, for starters.
