In no particular order, we present one of the fastest growing and extremely loyal aspects of social networks. That would be the networks that revolve around Music. Music being the social creature that it is, it is no surprise that this aspect of social networking is so attractive and so appealing to so many. So the fact that social networks, not the least being Myspace, which is the mother of all music social network sites, has evolved so quickly is no big surprise. Look for this sector to continue to explode and surprise as it straddles the hump between Web 2.0 and Web 2.5 within the next year. If not already. Feel free to add!
