On the release date (Aug. 11) of Kesha’s new album Rainbow, the singer shares an emotional essay published on Refinery29 about how music and crafting the record was what kept her going while she was in rehab. In her latest write-up, the singer reveals that she had to beg her rehabilitation center to allow her to play an instrument during her stay -- and when they eventually gave her an hour a day to play the keyboard, these were the hours she spent focusing on what became her new release.

“Writing songs is the only way I know how to process things,” Kesha wrote. “The whole album idea and tour and everything, came from me crying and singing and playing and dreaming until my hour was up and they took the keyboard away again. Every day I would just cry and play that song because I knew I had to get through that incredibly hard time. I knew I had to change and learn to take care of and love myself, and I had no idea how to even begin.”

Though the recording artist had a difficult time, she explained that writing the title track gave her strength to carry on. "'Rainbow' was the beginning of me turning that around and being kind to myself. It is a reminder that I can make it through anything. I hope this song exudes hope and self-love, because each of us deserves it," she said.

Kesha's new album comes amidst her on-going legal battle with producer/songwriter Dr. Luke. And while she has been through a lot in recent years, the singer explains she will never let go of her love for music and her belief in herself.

"There’s a line in 'Rainbow' that I really love: 'What’s left of my heart is still made of gold.' I truly believe that," she added. "It's true for me and it can be true for others, too. I know giant pieces of my heart have been held captive in the past. But not anymore. And what's left is f--king pure gold and no one can touch that."
