There are a few different ways people can buy music online, but they are all basically the same whether it by the iTunes Music Store, eMusic, Amazon, ro any other retailer.
PEOPLES MUSIC STORE is a bit different, as it is setup and run by YOU, the music fan. And unlike that alleged Ponzi scheme BURNLOUNGE from a few years ago, you don’t have to pay any money to participate.
All you have to do is select the music you want to sell, write a few reviews and articles, and post your links for people to buy from you. You’ll be able to promote your store by including code on your own website, or by using Widgets on places like MySpace or Facebook. The better you are at providing reviews and commentary, the more visible and profitable your storefront will become.
I’d call the whole thing “MyTunes”, but that name is already taken.
