Win the battle in your own mind first. Surround yourself with family and friends who share a similar vision and avoid those who have a negative attitude. Before you win the fierce battle with your competitors, make sure you've won battle with your own mind to persist no matter what it takes. When I left Kansas, friends told me I was just a church organist and not a Vegas singer. After nine years, I had sung and played every room in Reno, Tahoe, and most in Vegas. When I left to go to LA to write, musician friends said, "you're just a musician, you'll never make it as a writer." Now, 100 cuts later I don't hear much from them.
There are a lot of people approaching me or respond to my approach for either publishing their music or using their demos for pitching to the bigger names in the industry. I can say about 40% of the demos are receive are okay in sense of professionalism but the other 60% usually have some sort of issue which makes the project to don't move forward. Here I list down some of the common issues and the solutions for them.
Decide what you want. Before sending your track or your demos to a publisher or a producer, make sure at least you know what you want, and it would be even much better if also be open for their suggestions too. When you are sending them a demo, do you something in mind? If you had the power to get the song in whatever direction that you wanted, what would you do with it? All these and things like these are what you need to prepare before sending your demos out. Don't be confusing and don't make people confused. At the end of the day, this is your project and you want it to move forward, right?
