Sound Check (Gravity) by Gorillaz delves into the theme of existential weight and the pressures of life. The song uses 'gravity' as a metaphor for the burdens and challenges that pull people down, preventing them from reaching their full potential. The repetitive nature of the beat and the lyrics underscores the feeling of being trapped in a cycle. Vocalist 2D's delivery conveys a sense of introspective struggle and yearning for relief. Notably, the line 'We are the monkey' can be interpreted as a reflection on human nature and its limitations, suggesting that we are often the cause of our own struggles.
