Pop star Rachel Platten recently visited the Children’s Hospital in Los Angeles when she learned through social media that her song "Fight Song" was especially influential to one patient.

Jeremiah Succar was diagnosed in May with stage-four atypical rhabdoid teratoid, an aggressive, fast-growing tumor that occurs in the brain and spinal cord. Jeremiah has had one song in his head to help him through his treatments. So, when Rachel Platten showed up to sing ‘Fight Song’ with him, you can imagine how happy he was.
