"The very nature of a horror film is to elicit fear, to evoke literal nightmares and terror. A film's score is an integral aspect of the medium that shapes its mood, emotion, and atmosphere all without uttering a single word; for horror, it's perhaps more important than all other genres. Horror's sound and the scores are just as essential to spooking the audience as the on-screen kills, monsters, maniacs, and scares."
"A theme song is a signature tune that becomes associated with the film itself, and a go-to representation of the score. We wanted to dig into the genre's best original theme songs, those memorable music numbers that are talked about time and time again; the songs that have become iconic in their own right. Some even changed the way film scores were made."
