We are in the process of helping to re-design http://www.m4tr.co.uk. There are plans to incorporate a section dedicated to independent artist who have released their music on iTunes, Amazon etc. We have become increasingly aware of the bias 'mainstream acts have on all commercial download sites. If you send m4tr your Amazon and iTunes links to your release(s) they will incorporate into a dedicated section on their site.
