In 2019, the digital music landscape in Brazil witnessed a significant nostalgic movement centered around the keyword phrase “MPB Antigas As Melhores” (Old MPB, The Best Ones). This paper analyzes the sociocultural and commercial factors that led to the resurgence of classic Música Popular Brasileira (MPB) from the 1960s-1980s within streaming platforms. Focusing on playlists, user-generated content, and the collective memory of Brazilian listeners, the study argues that 2019 served as a pivotal year for the revaluation of artists such as Elis Regina, Tom Jobim, Chico Buarque, Gal Costa, and Milton Nascimento among younger audiences (Generation Z and Millennials). The paper concludes that the phenomenon was driven not merely by nostalgia but by a search for lyrical depth, melodic complexity, and cultural authenticity in contrast to mainstream 2019 pop productions.

On Instagram and Tumblr, a specific visual-textual aesthetic emerged: faded photographs of Rio de Janeiro, grainy video clips of Elis Regina performing on TV Globo, paired with existential captions. This “saudade chic” movement propelled MPB as a marker of refined taste among urban youth.

The trend was not without criticism. Some music journalists argued that reducing complex political works (e.g., Chico Buarque’s critiques of the dictatorship) to mere “relaxing background music” constituted a depoliticization of MPB. Conversely, defenders noted that even decontextualized streaming created new royalty revenue streams for aging artists and their estates.
