"Trouble" is a song by British rock band Coldplay, for their debut album, Parachutes (2000). The band wrote and co-produced it with British record producer Ken Nelson. The song's arrangement is built around the acoustic piano.
"Trouble" was released on 23 October 2000 as the album's third single, reaching number 10 on the UK Singles Chart and becoming the band's second top 10 single in the country. Although "Trouble" failed to chart in the United States, the music press deemed it almost as successful as its predecessor, "Yellow".
Two different music videos were released: one for Europe and another for the United States, which is currently the only one available on the band's official YouTube channel. There is also an associated release titled Trouble – Norwegian Live EP, which came out in the summer of 2001 and consisted of five tracks recorded live by the band at Rockefeller Music Hall in Oslo. It was released exclusively in Norway, being Coldplay's fourth EP and first live release.
