Which music fans are the most loyal? Spotify has attempted to answer that question by conducting a study, which was recently published to their Insights blog.

“To find out, we first identified the “core” artists that, according to The Echo Nest (a part of Spotify), are most central to each genre, starting with the big ones, on a global level,” the study reads. “Then we did  the same thing with local genres in various countries around the world. To create a measure of genre loyalty, we divided the number of streams each core artist had by their number of listeners. All of the charts are normalized against the genre with the loyalest fans.”
