To quote from musiclover's original post:

"They get lots of friends on facebook, then simply share the link to their music on youtube etc and obviously if the stuff is good the friends will share with other friends etc.

So the whole thing just builds and builds."

In my opinion, there is no magic in use of social networking, other than it has less corporate influence as to what can become popular. Simply sharing music on Facebook or any other social network site - like SoundCloud is specifically for music - requires something that appeals to masses to become popular. It requires work to build the friend collection, etc. It doesn't just build and build all on it's own.

Plain and simple.

There's actually a decent assessment of how to build a listener base on the SoundCloud site. Here's the link: http://help.soundcloud.com/customer/portal/articles/1209774-how-to-grow-your-soundcloud-community

This applies on all kinds of scales as it pertains to social networking. There is work in gaining 'friends or followers'.
