Production music, also known as library music, is a type of music specifically created for use in media projects such as films, television shows, advertisements, and video games. This music is often composed and recorded in advance, allowing creators to license it easily for their productions without the need for custom compositions. Typically, production music is organized into libraries, where users can search for tracks by genre, mood, or instrumentation. This makes it convenient for filmmakers and content creators to find the right sound to enhance their projects while saving time and resources compared to hiring a composer or musician.
