On Wednesday, Cleveland.com announced that the woman who was held captive for more than a decade has written a song called "Survivor," which will be available on May 19. The site mentioned that Knight was writing the lyrics to this tune during her kidnapping when Ariel Castro had her locked up in a house for all those years.

Writing songs was one of the things that kept Knight is focus during the years she was chained up in a room encountering numerous forms of abuse.

"In the house, I wrote all the time, poems and songs," the 34-year-old said. "And since I didn't have any instruments to play, I would just hum a melody and sing."

See below for a brief version of the song. It starts off with a reporter describing the horrific yet miraculous incident when Knight and two other girls- Amanda Berry and Gina DeJesus- were kidnapped by Castro and trapped inside a house for approximately a decade before all three of them found their salvation. Knight then sings about how what does not kill her can only make her stronger.

During their captivity, the girls experienced beatings, rape and more torture until May 2013 when Berry found a way out of the bedroom and tried to kick a door down to get out. A neighbor helped her when the cops were called and the girls were saved.
