Have you ever wondered what makes a song sad? Is it simply lyrical content? Is it the personal feelings you prescribe to that song, your recollections of it? Are there simply chords or intonations of voice that can stir this feeling in us. Is it scientific or formulaic? Certainly there are artists who are known as dark, or depressing but even some of these artists have other tracks that are more buoyant or jubilant. If you are interested in these answers or simply like most of us, have compiled lists or mixtapes in your head of the saddest songs of all time, then this book is for you.
