The Feel Again Songfacts says that the song was inspired by children in remote villages who are in need of life-saving care. Part of the sales of the single were donated to Save the Children's Every Beat Matters campaign to support training frontline health workers around the world. According to the organization's website, when writing the song, Tedder drew on recordings of children's heartbeats for inspiration.
It's been a long time coming since I've seen your face
I've been everywhere and back trying to replace
Everything that I've had till my feet went numb
Praying like a fool that's been on the run
