This song was written by one of Anastacia's producers Jamie Hartman along with Phil Bentley and Shelly Peiken
. Anastacia first heard it the day she wrote "Pendulum
" and told Hartman she wanted to record the tune as she identified with the lyrics after battling breast cancer. However, the singer was told it was being held for The Hunger Games
. "The Hunger Games
didn't take it; so almost at the end of writing this album he asked me if I was still interested," Anastacia told Digital Spy. "There are songs I hear that I wish were mine like 'Crazy
' by Cee Lo. I feel like that was so my song! 'Lifeline' was the right song for me."
"Jamie wasn't sure if he needed to change a few of the lines that were inappropriate, because it was written about killing a friend. I said 'No, because I'm singing this song to cancer,'" she continued. "To be honest, cancer made me kill a part of myself. He didn't even think about it like that."
