"I do like to write nasty songs. It's a useful weapon to have, and it's cathartic as well, because I create art out of anger, something positive out of something negative"

This quote by Lisa Marie Presley talks to the power of art and music as a form of expression. Writing "nasty songs" is a way for her to take her anger and turn it into something favorable. It is a form of catharsis, enabling her to take her unfavorable feelings and create something beautiful out of them. Composing these songs is also a form of self-defense, as it provides her a weapon to use versus her opponents. It is a way for her to take her discomfort and utilize it to her benefit. By writing these songs, she has the ability to take her anger and turn it into something that can be shared with the world. It is a powerful form of expression that allows her to take her negative feelings and turn them into something favorable.
