The line comes from Coldplay's 'The Scientist,' released in 2002 on the album A Rush of Blood to the Head. Chris Martin sings it near the start of the song, as part of a reflection on trying to return to the beginning of a relationship. The track became one of the band's most recognisable ballads, and the phrase later took on a life of its own in short-form video. Creators reuse it as shorthand for effort, disappointment, and persistence, because almost anyone can recognise both the melody and the feeling behind it.
