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

"Women's solidarity derives its strength from the bond of sisterhood. This invisible bond between us goes back centuries, perhaps to the times when we were wise, artistic and healing witches... Unfortunately, although that core bond of sisterhood that holds us together has thinned over time, it has never been broken 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. 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" emerged with exactly these feelings.
