Meaning of "Mind" by Declan McKenna

The lyrics of "Mind" delve into the complex emotions and thoughts of a person who is caught in a confusing and tumultuous relationship. The protagonist feels lost and isolated, symbolized by the line "Deciding the loneliest heart in the living room, was mine." They see themselves as separate from others, experiencing envy and pride as the only escape. The reference to the deadly sins suggests that the protagonist is aware of their own flaws but also feels justified in their actions. The repetition of the question "Why'd you keep changing your mind?" reflects their frustration towards their partner's inconsistency and their own inability to make sense of their emotions. The mention of a plastic bag and dependence on wine portrays the protagonist's search for comfort and escape. Ultimately, the song conveys a sense of confusion and a longing for stability and understanding.
