This research focuses on two distinctive determinants of DJ popularity in Electronic Dance Music (EDM) culture. While one's individual artistic tastes influence the construction of playlists for festivals, social relationships with other DJs also have an effect on the promotion of a DJ's works. To test this idea, an analysis of the effect of DJs' social networks and the audio features of popular songs was conducted. We collected and analyzed 713 DJs' playlist data from 2013 to 2015, consisting of audio clips of 3172 songs. The number of cases where a DJ played another DJ's song was 15759. Our results indicate that DJs tend to play songs composed by DJs within their exclusive groups. This network effect was confirmed while controlling for the audio features of the songs. This research contributes to a better understand of this interesting but unique creative culture by implementing both the social networks of the artists' communities and their artistic representations.
