Many of us like to listen to music while we work. It’s become a ritual, alongside the coffee in our favourite mug. Previous research suggests this is probably no bad thing. In lab studies, people who listen to music they like, generally perform better at mental tasks afterwards, an effect that’s been attributed to boosts in mood and arousal.

Nick Perham and Martinne Sykora made a counter-intuitive prediction - background music that you like will be more detrimental to working memory than unappealing music, so long as the liked music has more acoustical variation than the disliked music.

So, the next time you’re bothered by someone else’s bad music, console yourself that the noise could be less harmful to your work performance than your own choice would be!
