“Pyro” is a soft song similar to “Knocked Up” off of 2007’s “Because of the Times” or “Milk” off of “Aha Shake Heartbreak”. The verses start soft and build into the chorus which coasts at a soft effective sound. The chorus also has a similar arena sound to “Radioactive” but with a slower and softer pace. The soft sound of the song matches the lyrics as it tells the sad story of a man about to burn everything around him.
