From my research I have found out Niche music can promote themselves in as many different ways as mainstream artist or more. This proves the long tail theory. As independent music sell slowly therefore it is not widely available on high street or supermarket. Due to the limited phyical spaces in a shop, so Niche music will not tend to be stocked, because they don’t sell enough copies to earn their shelf space. This makes internet the home of Niche music. Storing music digitally do not take up physical spaces so sites like Amazon and Play.com, can have infinit amount of Niches music. This allow these sites to make big money, even though one sell every now and then. But there are infinit amount of different ones so increase the chance of selling. As independent artist do not have the amount money to promote themselves as mainstream artist. Promoting themselves online is considerably cheap compare to television adverts and posters. By giving away free music to increase popularity so they get more fans and merchandise and concert tickets can be sold. 
I have learnt that both indepent music and maistream music is very easily get hold of. Also the price is slightly cheaper than high street stores. On the internet tracks can be downloaded instead of buying the whole album, which might have songs that the user does not like. Downloading tracks off the net will only take maximum few minutes. This saves a lot time from going to a high street store. As well as this, on the internet music can be searched and the price and be compared easily.
