Its a known fact that the everything changes but with change you are either with it or against it. It has become that making music is becoming something we can do even on our laptop. This has made it easier for anyone to become an artist to making music now a days. Though with this change it has becoming different for people to sell their music. Its more of selling directly to fans. How you can get people to support you and listen to because they want to. Not so much about whether you are good or not but whether you are there to fill the spot. I also agree with the wide range of the internet being use to distribute yourself. It is so much easier to be heard and to get noticed by having your stuff online for everyone to see. I think one of the best points here are to give your fans a reason to buy and a reason to listen. Why are you any different than everyone else making music? It might be your interesting or its all going to a good cause. Give them a reason to want you and support you.
