Several studies have recognized that listening to music while working affects the productivity of people performing complex cognitive tasks.[82] One study suggested that listening to one’s preferred genre of music can enhance productivity in the workplace,[83] though other research has found that listening to music while working can be a source of distraction, with loudness and lyrical content possibly playing a role.[84] Other factors proposed to affect the relationship between music listening and productivity include musical structure, task complexity, and degree of control over the choice and use of music.[85]
