'Who Can Say' is a song by Irish singer Enya from her fifth studio album, A Day Without Rain, released in 2000. The album is known for its layered vocals, soft synthesisers and peaceful, atmospheric production, and this short phrase captures that style in just a few seconds. Online, the clip has been reused in video edits and montages, often to signal a gentle shift in mood or a moment of reflection. It remains popular because it is instantly recognisable, easy to place, and short enough to work as a transition without overpowering the visuals.
