Kesha has released her first single in three years, “Praying”, after announcing it yesterday via Instagram. The singer has been locked in a lawsuit with former producer and collaborator Dr. Luke for three years; she sued him in 2014 for sexual assault and battery, sexual harassment, gender violence, emotional abuse, and violation of California business practices and was subsequently locked into an ugly battle with Sony to be released from her contract. Earlier this year, a judge refused to amend her original case, claiming that Dr Luke's alleged abusive behaviour was “foreseeable”. Kesha has not released a single in four years because she did not want to work with Dr Luke, despite the fact that she had “dozens if not hundreds of songs ready for release”, and Sony would not allow her to leave and release music elsewhere. However, Dr. Luke was dropped from Sony and Kemosabe records in April, so she is now relatively free.
