The song "Choice" by Jack Stauber's Micropop is about the conflict between the different parts of our brain and body that control our emotions and actions. The lyrics mention various substances such as caffeine and melatonin, which affect our behavior and mood. The singer addresses someone they have just met, asking who they are. The other person identifies themselves as "injury," but the singer insists that they have a choice in how they define themselves. The chorus repeats the words "Love, brain, heart, control" and "Caffeinate!" emphasizing the role of these different factors in our decision-making processes. The lyrics suggest that these parts of ourselves are in constant conflict, with the brain and heart vying for control over our actions. Overall, "Choice" is a commentary on the complex and often confusing nature of human emotions and the struggle to make choices that align with our true desires. The repeated smack at the end of the song suggests the frustration and physical toll of this internal battle.
