“Fight Song” has been Jeremiah Succar’s anthem since May. The 7-year-old has stage-four atypical rhabdoid teratoid, a rare and aggressive form of cancer that occurs in the brain and spinal cord. He learned all the lyrics and even got to sing them with the songwriter herself, Rachel Platten, on his hospital bed at the Children’s Hospital Los Angeles. “This is my fight song / Take back my life song / Prove I’m alright song / My power’s turned on / Starting right now I’ll be strong.” If you need some melodic punch to help you make it through something, this could be your fight song too.
