Here are a few useful sites I’ve found whilst researching how to start advertising and and selling my music without having to pay anything. Hope it helps!

• Bandcamp is probably the best website regarding ease and freedom of music sale. You just upload the tracks and album art and name your price. They take 15% commission, and PayPal take a little too, but if you read through their FAQs there’s plenty of information and advice to help you manage your music independently. UPDATE: Bandcamp now have a facebook app, so it’s possible to sell music via facebook pages. Here’s the info: http://bandcamp.com/facebook_app.
• RouteNote are advertising that they can get your tunes on itunes, and you don’t have to pay anything up front as they take a percentage of the money from sales. If salesincrease you can pay a flat rate each month and keep all of the money from your sales.
• RootMusic have quite a neat module for playing music on facebook pages. If you want to customise it, you have to pay,but the free version looks quite tidy and does the job. You can also use a facebook app by ReverbNation, but in my opinion it didn’t look so tidy.
• Get British Businesses Online will give you 2 years worth of free domain name. The only catch that I can see (other than the fact that you have to be based in Britain) is that you have to use google sites to build a website.

If you’ve found any other useful sites like this, please don’t hesitate to comment!
