In the brazilian dictatorship (1964-1985), there was no freedom of expression and, because of it, artists had to use their creativity a hundred times more carefuly. If their work wasn't approved by the militars who controlled what could be divulgated, they'd be tortured to death.
So, here's a playlist of some songs that passed by militars' test and some that didn't.
