Under the copyright law, an author or creator owns a copyright in his or her work the moment it is "fixed in a tangible medium" (i.e., the moment the expression of an idea is written down or recorded in some manner). When it comes to the recorded music business there are two primary copyrights of interest: one in the musical composition or song; another in the sound recording of that song. A copyright extends for the life of an author plus 70 years, and in the case of collaborators on a copyright it extends for the life of the last surviving collaborator plus 70 years.
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?
