Good post for those music marketers out there....
I agree with this assertion - because music is a relatively risk free consumption commodity the complex contagion model is not so applicable here. Consumers are often on equal footing with regard to music, although certain network hubs (Anatomy of Buzz by Emanuel Rosen - also a good read) have more influence than other members of networks if only because of sheer network connections. Instead of trying to force the public to like your music (which is possible but both frustrating and expensive) it seems easier to let them come to you.
