On Friday, a New York judge denied Kesha's injunction against Dr. Luke leaving her legally bound to her contract with the producer amid allegations that he has sexually, physically and verbally abused her.
Artists from around the industry then began showing their support for the singer on social media including Demi Lovato and Swift who has later reported to have donated $250,000 to Kesha.
Another producer, Zedd, also pledged that he would help with new music, posting "Very very sorry to hear about the whole situation. I'll be happy to produce a song for you if you want my help."
