Similar to how the Zoo TV Tour display screens sampled video footage from television programming, a number of songs from "Zooropa" sample audio. The introduction to the title track, "Zooropa", contains a noisy collage of indecipherable human voices from radio signals—credited to the "advertising world"—played over sustained synthesiser chords. The industrial-influenced "Numb" features a noisy backdrop of sampled, rhythmic noises, including "arcade sounds", a Walkman rewinding, and a Hitler Youth boy banging a bass drum in the 1935 propaganda film "Triumph of the Will". "Daddy's Gonna Pay For Your Crashed Car" begins with a snippet of fanfare from "Lenin's Favourite Songs" and samples MC 900 Ft. Jesus' song "The City Sleeps".
