If you have a CD of your music, one of the best ways to make money online is on a site called CD Baby.You furnish them with five cds and they put up a sample of each song if you wish, and, people can hear the samples for free and then purchase if they want. Also, your songs will go out to a lot of places such as ITunes if you wish, where you make money per click. CD Baby gets a percent of sales, but, they do all the shipping and provide the service of sending your music to ITunes etc. Your initial cost is about $100 or less. It has been a while since I have did this, so, some details may have changed. If you have a CD and decide to do this, I personally would take one song and place it on YouTube, and, then link it to places such as Hubpages, Facebook, etc.
