The song was released in 2005 and quickly became one of her most recognizable songs. The title comes from a statistic about Beijing, where Melua once visited — a city said to have nine million bicycles. That small detail turned into a larger idea: even in a world full of facts, doubts, and unanswered questions, some feelings don’t need proof.
The melody is soft and restrained, giving space to the lyrics rather than pushing them forward. The song doesn’t argue or explain itself. It simply offers a belief — that love can be certain, even when everything else isn’t.
