For elite athletes, being able to tune out distractions is practically a requirement. But that doesn't mean it comes easy. To prepare for matches at this year's Olympics, some athletes are now listening to music composed by robots. According to Newsweek, the U.S. wrestling team has turned to Brain.fm, a startup that makes tunes meant to help listeners relax, focus, or go to sleep. The music contains barely detectable vibrations that align with the frequencies naturally emitted by the brain, according to the company.

Argentinian goalkeeper Sergio Goycochea used to urinate on the pitch, certain French rugby players like to headbutt each other and Serena Williams apparently never changes her socks during a tournament--but as athletic rituals go, listening to music composed by a robot has got to be up there. In an effort to get one up on their rivals, the U.S. Olympic wrestling team has been listening to songs written by artificial intelligence to prepare for matches.

Lindland approached science journalist Steven Kotler, who recommended the AI-composed music as a safe and healthy performance-enhancing technique.
