When you mentioned a Chilean song of protest I immediately thought of "Y la culpa no era mía, ni dónde estaba, ni cómo vestía".

It went viral a few years ago as Chilean women spoke up regarding the violence they were subjected to. I just realized how fitting that song was to the cause. It was reprised and performed in multiple countries and it's still fresh enough for women around the world to still feel moved by it (the lyrics literally popped up in my mind as soon as I saw your post).

I'm posting a link, it could be a good idea to translate it (I could help as much as I can but would need help). See if it gets picked up in Iran; it could have a massive impact worldwide if it does.

It loosely translates to "it's not my fault, nor where I was, nor how I dressed". The song is really catchy, easy to memorize and might ignite more fervour from the protestors than the current songs do. The current songs are beautiful but may be a tad too melodious to march to, protest to or translate resilience and revolutionary ardor.

Sorry I went on a tangent. That song and video you posted were beautiful, thanks for sharing.
