The lead single for their debut studio album Olhar, which would come out in the following year, it was the band's first official release under the name "Metrô" (they were known as A Gota Suspensa from their foundation in 1978 until 1984) and their first of many releases under the Epic label.
The song was a huge hit, and was responsible for catapulting the band into fame.
The second one was made for their 2002 album Déjà-Vu, and is a bossa nova-inflected version of the song.
A remix of the song by DJ Zé Pedro was subsequently included on the 2016 re-release of Olhar as a bonus track.
Brazilian singer and TV presenter Angélica has covered the song in her seventh, self-titled studio album, released in 1994.
