• "Purge The Poison" finds Marina drawing on historic pop culture moments like Britney Spears' meltdown when she shaved her head and Harvey Weinstein's role in the #MeToo movement. She also takes on political topics such as the lack of female parliamentarians worldwide and the failures of capitalism.
  
  During the pre-chorus and chorus, Marina proposes that the COVID-19 pandemic has created the opportunity to purge the system of corrupting forces and we should start again with a new world order.
