In most instances, the actual recording you submit is what will be used in the film or TV show. It will not be re-recorded. The primary exceptions are songs that play over the credits at the beginning or the end of a big Hollywood movie; the opening or closing of a TV show; or a song included in a commercial. In these instances, a new version of the song might be recorded. For example, Celine Dion might be hired to record the song to be used as the credits roll during the sequel to Titanic. Typically, the music you submit will be used “as is.” That’s why the musicianship, the vocals, and the overall sonic quality has to sound almost indistinguishable from the songs you hear on the radio. This is sometimes referred to as broadcast quality.
