Grooveshark's beluga project (http://beluga.grooveshark.com) reveals a lot of the same patterns. Looking up Mormon tabernacle choir, for instance, shows a high listenership of politically active, religious conservatives, while people that listen to system of a down tend to be moderate liberals with less political involvement.

Music demographics data is fascinating!

This is far more interesting than the linked article, mostly because it actually shows data for the music that I listen to.

For example, Paul van Dyk, Three Drives, and Ferry Corsten all have "IT Specialist / Programmer" as highly over-represented (wow!).

In addition, Tiësto (had to look up Tiesto) shows that advertising does in fact, work! ... 92% of the listeners on Grooveshark uses Windows Live Spaces.

He was hired by Microsoft to sell Vista to the Dutch market: http://www.reuters.com/article/2007/04/15/music-tiesto-dc-id...

Good find! :)
