This record marked a turning point in songwriting, as for the first time, songs created by Claudio Narea and Miguel Tapia were included, in addition to Jorge González. A notable example is Lo estamos pasando muy bien, which was originally composed and sung by Narea. The album's themes were highlighted by its open critique of Augusto Pinochet's dictatorship, with songs like Poder elegir addressing this stance forcefully. This lyrical bravery led to Los Prisioneros being censored and banned in many places, and to the media labeling them as "harmful to youth".
Among the ideas that did not make it onto the album was a demo titled Lo estamos pasando muy mal, a spoken-word piece about a repression agent. The reaction to this track was so strong that its publication was considered likely to cause serious problems. Other songs, such as San Miguel, composed by Jorge González in 1987, did not find a place on this album but would be recovered years later, in 2003. The singles that propelled this work were We are sudamerican rockers, Maldito sudaca, Lo estamos pasando muy bien, Que no destrocen tu vida, and Pa pa pa, of which the first three had music videos.
