Personification is when objects or non living things have human qualities. For example: "Her hair was just crying out to be brushed," her hair wasn't really crying out, but you get the point. "The long grass danced in the wind," grass doesn't dance. So that's personification! Hope it helps! :)
i think it is because people can express their feelings in songs about their love life, or just life in general. I think it is a good way to express your emotions.
