A ghostwriter is a professional writer who is paid to write books, articles, stories, reports, or other content which are officially credited to another person. Celebrities, executives, and political leaders often hire ghostwriters to draft or edit autobiographies, magazine articles, or other written material. In music, ghostwriters are used in classical music, film score composition, and popular music such as top 40, country, and hip-hop. The ghostwriter is sometimes acknowledged by the author or publisher for his or her writing services.
