Does digitization lead to the homogenization of cultural content?
利用1990-2015年10国音乐榜单数据，分析数字化是否导致音乐内容同质化，发现流媒体时代（如Spotify）反而显著提升了声学多样性。
Abstract Using weekly music charts data in 10 countries over the period 1990–2015, we analyze whether digitization leads to a trend of homogenization of music content or conversely to a greater acoustic disparity. We split the digitization era in four periods that correspond to four new emblematic distribution models (Napster, iTunes, YouTube, Spotify). Our main result is that while acoustic diversity decreased during the iTunes and the YouTube periods, the period that begins with the introduction of audio streaming services, such as Spotify, represents a turning point and is marked by a significant increase in acoustic diversity.
