I know myspace and that. But like how do they stop lots and lots of other sites taking business from them? it seems there is only one site like spotify and facebook monopolizes the market. But it must be fairly easy to set up a similar site...

that is a good question these days there is lots of competion on the internet every social networking site is trying to make theres better facebook is the only one thats winning myspace has choosen to do squat same thing with anything else

Try grooveshark.com you will be amazed it is far superior to spotify and to go vip is 3 dollar a month there is also a app for your phone

How do sites like spotify and facebook stop similar sites existing?
