The song "Brass Knuckles" by Living Things is about the frustration and anger towards the violence and conflict happening in the world. The lyrics talk about the desire to take to the streets and fight for change, to rally against the injustices and stand up for what is right. The line "I got wounds down deep, I got a holocaust" could be interpreted as a metaphor for the emotional scars and pain caused by the suffering and atrocities witnessed in the world. The reference to Ritalin and guns ready in the line "We got Ritalin and guns, we are ready" could be a commentary on the prevalence of drug use and violence in American society. The chorus encourages the listener to join in and take to the streets, to run with the singer and stand up against the apathy and pain. The mention of brass knuckles could symbolize the idea of fighting back and taking a stand, using whatever tools are necessary to make a change. Overall, the song expresses the frustration and determination to bring about change and make a difference in the world, urging others to join in the fight for justice and equality.
