There are many misconceptions and much confusion about copyrights, some of which are encouraged by industry people. Rather than 100 percent writer's copyright, the music industry generally accepts a song that is 50 percent writer's rights and 50 percent publishers rights. Even if you just wrote your first song, you are, by this definition, a music publisher the minute you write out the words or record yourself singing it. Copyrights are what drive the economy of the music industry, so understanding them is crucial.
Publishing companies want that 50 percent of your copyright assigned to publishing rights. In reality, they have a tough job to do, putting your song in the hands of the right people at the right time. You could do this yourself and keep the rights, but most aren't connected well in the industry. Assigning publishing rights to a record label or publisher is common and indeed necessary for a new artist.
Writer's share is often referred to as "100 percent writer's share," but don't be fooled. It is still only 50 percent of the money earned by the song. Many managers and promoters want to get a piece of that action for the royalty income it represents. A 20 percent commission on a single concert pays them once, while the same on royalties pays them over and over, and it comes from your share of earnings.
If a promoter or manager is arranging shows for you, you need to consider how it will support your career. Protected copyrights may bring you more money through increased exposure and therefore it may be worthwhile to allow a promoter a greater share on single concerts. Making money is, of course, why you are considering management, and it is why people are in the business. Finding a balance of trust is key, and it is difficult.
The music business is a rat's nest of contracts and agreements. In a world where 50 percent equals 100 percent, having a trusted legal resource is essential. A lawyer that specializes in entertainment law is ideal, but a trusted contracts lawyer is better than none at all. The music industry attracts people who can sell you the stars. A lawyer can save you from unfair contracts by providing a dispassionate eye trained to read the language.
