Tango lullaby / Early education

I came across a sweet lady at a milonga recently. She told me about her kids and I asked her if she ever teaches them tango. She replied, "they don't need to be taught, they already do it without instruction!" She continued by telling me that she listened to tango music throughout her pregnancy with her first child. After birth, she used to take her baby to afternoon milongas, and if the baby was crying, it'd immediately stop crying as soon as it could hear tango music!

Aahhh....
