Abstract: | Can live music events generate complex contagion in music streaming? This paper finds evidence in the affirmative—but only for the most popular artists. We generate a novel dataset from a music tracking website to analyse the listenership history of 1.3 million users over a two-month time horizon. We show that attending a music artist’s live concert increases that artist’s listenership among the attendees of the concert by approximately 1 song per day per attendee (p-value < 0.001). Moreover, this effect is contagious and can spread to users who did not attend the event. However, whether or not contagion occurs depends on the type of artist. We only observe contagious increases in listenership for popular artists (∼0.06 more daily plays per friend of an attendee [p < 0.001]), while the effect is absent for emerging stars. The contagion effect size increases monotonically with the number of friends who have attended the live event. |
