Infographics: Artist Map

Paul Lamere of Music Machinery made this interesting map of favorite musical acts by state. This map is not a map of the most played artist in each state, one requirement was that only one artist could be assigned to each state.
Paul explains "For this study, I sampled the listening preferences of about a quarter million listeners that have a zip code associated with their account. update: Listener data is drawn from a variety of music streaming services that are powered by The Echo Nest. I aggregated these listeners into regions (state, regional and all-US). To compare regions I look at the top-N most popular artists based upon listener plays in each region and look for artists that have a substantial change in rank between the two regions. These artists are the artists that define the taste for the region."
