The use of library music in TV shows can add an extra layer of emotion and depth to a scene, without the cost and time of commissioning a custom score. Library music, also known as production music, is pre-recorded music that can be licensed for use in various types of media such as films, TV shows, and commercials.

One advantage of using library music in TV shows is the cost-effectiveness. Commissioning a custom score for a TV show can be costly and time-consuming, whereas licensing pre-recorded music can save a production budget and time.

Another advantage is the variety of options available. A music library typically has a wide range of music genres and styles, making it easier to find the perfect track to fit the mood and tone of a scene. This can also allow for more creative freedom in the scoring process.

Additionally, using library music can also save time in post-production. With pre-recorded music, the music can be selected and licensed before filming even begins, allowing for a smooth integration of music and picture during post-production.
