Rewşan and Tara Mamedova's duet single "Xuçê", (Sister) was released on all digital platforms on Friday, March 4, 2022. The song, whose lyrics belong to Tara Mamedova and music by Rewşan, was distributed on digital music platforms by Believe.

"Women's solidarity draws its strength from the bond of sisterhood. This invisible bond between us goes back centuries, perhaps even to the times when we were wise, artistic and healing witches... Unfortunately, that core bond of sisterhood that holds us together has never been broken, even though it has become thinner over time, because we are still those strong witches who sing, dance and embrace each other with compassion. We try to strengthen the bond between us with love. And we do this for ourselves, for all of us and for a better world. Because we are each other's home." And the song "Xuçê" was born out of this feeling.
