There are many events so far in 2026 that could reasonably have been predicted, but perhaps one which couldn’t is a Hackaday scribe in Europe unexpectedly finding herself with a constant earworm from Afroman. The rapper, who most of us know only from his year 2000 hit single about getting high, made the news after an inept police raid on his house, and in turn a court case over his musical denunciations of the authorities.

It’s fair to say they picked on the wrong guy, but in thinking about why, the answer is in the earworm. He has the unique skill of making a song irritatingly catchy, which led us to the question of how a catchy song works. As luck would have it a team from the University of Waterloo have recently released a paper in which they explain it all in terms of maths, giving the rest of us a formula where the likes of Afroman are presumably born with it.

We won’t pretend that Hackaday’s mathematical expertise stretches beyond that needed for engineering, but for the more advanced numberphiles among us the university’s write-up goes into some detail about their use of group theory to study the patterns and symmetry in a given piece of music. It’s a new approach that joins other more famous guides to musical success, so perhaps if you couple it with the stuff your music teacher failed to tell you in school, you could be on your way to the top of the charts. Meanwhile here at Hackaday we’ll stick to more conventional inspiration.
