scientism, technicism, and economism. The final track from Achtung Baby, "Love Is Blindness", is described as "an interpretive bridge into the land of Zooropa", which Vagacs explains is the setting for the album, as well as the setting for songs on U2's following album, Pop. "Beautiful Day", the opening song from U2's 2000 album, All That You Can't Leave Behind, describes "a fresh start in Zooropa". The use of consumer slogans as song lyrics was also commented on by various sources. Critic Perry Gettelman interpreted them as meaning to "signify the emptiness of modern, godless life". Kieran Keohane of York University stated that the slogans in "Zooropa" were to express an alienating form of interpellation, while J. D. Considine of The Baltimore Sun referred to the slogans as a parody of the economic hype used to pass the Maastricht Treaty, through the promising of impossibilities, such as "Be a winner" and "Eat to get slimmer". English professor Kurt Koenigsberger of Case Western Reserve University stated that the consumer advertisements constitute Zooropa as a "sardonically dystopic" location. In the book Reading Rock and Roll, Robyn Brothers said that the song conveys a "sense of confusion in the wake of a technology speeding beyond our control", while referencing the lyrics "I hear voices, ridiculous voices / I'm in the slipstream". Brothers also compared the song to "Acrobat", stating both songs reference a response to uncertainty and an unavoidable feeling of alienation. Legacy Zooropa producer Flood said that "Zooropa" was one of his favourite songs on the album, along with "Daddy's Gonna Pay for Your Crashed Car", "The First Time", and "Numb". Mullen felt that the song was "absolutely mesmerizing". Following the release of "Zooropa", references to the song have appeared in professional writings and in other media. On the day of the U2 concert in Sarajevo during the PopMart Tour in 1997, tour set designer Willie Williams wrote about waking up that day with "Zooropa" playing in his head and stated that Sarajevo "is the city of Zooropa, if there ever was one." José Manuel Barroso, president of the European Commission, quoted the song's lyrics at a 2005 press conference after enlisting Bono in an effort to get governments in the European Union to give more money to developing countries, and stated that the lyrics inspired an article he wrote about the future of Europe.
