A Message is a track from Coldplay's 4th album, X&Y. After lead singer Chris Martin let close friends hear a preview of the album before release, one commented saying that X&Y was "missing something". Martin wrote A Message in the middle of the night, describing it as "the only Coldplay song I've written without clothes on".
In 2005 in Q Magazine, Martin stated "A Message is my favourite song, it's the simplest. It arrived with 10 days of recording left so it was very exciting to do. It took a day and a half to record." .
