A bit OT - but having grown up in Finland, I always get extreme nostalgic feelings whenever tango comes up. For whatever reason, Tango was (probably still is) huge over there - unlike the other countries up here in northern Europe.
While other neighboring countries had what is essentially called "dance bands" (think smooth muzak version of country/western music), the Finns kept to their minor-keyed Tango.
You can trace a lineage from that German (?) cheese to Brazilian música sertaneja (country music), as in "Rumo À Goiânia" (Road to Goiânia), this rendition by Leonardo and Zezé di Camargo: https://www.youtube.com/watch?v=MEjGy20QQHk
My parents moved to one of the referenced towns, Uberlândia (Land for All) in the mid-1950s, and then to Goiânia itself later on. (Then Rio de Janeiro, Montevideo, Brasília. "Home" though always was Phoenix, AZ.)
One of the comments there: "Sem dúvida, é considerado um hino para os brasileiros, principalmente para população do Nordeste." ... "Without doubt, [this song] is considered a Hymn for Brazilians, especially for those in the Northeast [region of Brazil]." Northeastern Brazil lives through seven- or fourteen-year cycles of some rain then long drought, leading to many since the 1980s moving to big cities elsewhere in the country.
This is an interesting topic for me personally, and the way I experience it is like this:
The starting point to a musical scale, classically, is major. Minor is the first alt-culture in key signature.
However, the next step to get a major minor like, is the major 7th, or other half tones, like the 6th. Then, you have the converse, making minors major like, such as the melodic minor scale, or the minor 7th.
Interesting songs, especially in popular culture, make use of this dualistic view. Examples are Wicked Game by Chris Isaak (in a mode, where you don't regress to tonic, giving it an incomplete and spooky theme), Clocks by Coldplay (major chord, minor on 5th rather than major; major on 4th).
