[Reference] This is a reference to Zombie Flesh Eaters 2, in which the corpses of the deceased return to the world of the living as a result of burning one of the infected cadavers. The lyric "zombies stumble through the traffic" refers to the final scene of Zombie Flesh Eaters in New York, where the undead plague a bridge, and due to budget restrictions, the film makers couldn't afford to have the traffic stopped. Also, a sample from the movie can be heard at the start of the track. [Song]
