Behind the popular protest song is the artist Shervin Hajipour.
With the help of Twitter posts written under the hashtag "#Mahsaamini", he composed the song that describes how Iran has changed under the rule of the mullahs.
"Baraye" means "for" in Swedish and the song ends with the slogan "Women, life, freedom".
Shortly after the song's release, Shervin Hajipour was arrested and the song has been taken down from his social media.
Hajipour was then released on bail but is not allowed to leave the country.
In a statement on social media, he has distanced himself from the song and believes that it was misinterpreted and exploited by "groups outside Iran".
It is not clear whether the statement was coerced while Hajipour was in custody, but activists say it is highly likely.
Widely spread
Since the song appeared on social media, it has spread widely.
In October, British pop band Coldplay performed "Baraye" during their world tour in Buenos Aires with Iranian actor Golshifteh Farahani.
In Sweden, the song has, among other things, been performed in Swedish by Carola during a support gala for the Iranian protests in SVT.
It has also been interpreted by the Malmö Opera Orchestra and the artist Bahareh Razekh.
During Musikhjälpen it became the year's most requested song and in February it may be awarded at the Grammy Gala in Los Angeles under the category "Best Song for Social Change."
