"Perfeição" was a scathing rebuke of Brazilian government and society, inviting the listener to celebrate everything stupid, evil and ugly about the country. The song compares Brazil to a house of marked cards, a den of thieves, and a State that is not a nation, but the song explodes any pretensions of moral superiority towards the end by remarking on, above all else, the stupidity of the person singing the song. After the energy and anger of the main body of the song, this final section is almost wistful. The music continues to race ahead, but the vocal seems to be trying to pull it back, simultaneously celebrating and undercutting the belief that perfection is achievable, at least in the heart. The song's popular success is emblematic of the political changes that had taken place in Brazil since the band's inception: it certainly could not have been distributed during the days of Brazil's military dictatorship.
