"One" is a song by Swedish house group the Swedish House Mafia from their debut album Until One. It was released in the United States on 6 September 2010. A vocal version titled "One (Your Name)", featuring American singer Pharrell Williams, was released in the United Kingdom on 22 March 2010.
The song debuted on BBC Radio 1 with Zane Lowe on 19 February 2010. A month later the vocal version featuring Williams was played. "One" peaked at number two in Belgium (Flanders) and on the UK Dance Chart. It reached number one in the Netherlands, number seven in Ireland and in the United Kingdom on the UK Singles Chart. It also charted in Sweden, Switzerland, Denmark, Austria and Germany.
The song briefly became popular again in late 2014, with it being named as a favorite song in a Teens React video by the Fine Brothers.
"One" was written and produced by Axwell, Steve Angello and Sebastian Ingrosso. The lyrics in "One (Your Name)" are written by Pharrell Williams. According to Angello the vocals were recorded in Australia over a year, prior to the release, and were initially intended for another song. He said, "We took that and tried it on One and it worked. Well, it worked after Axwell Melodyne'd the crap out of it! [...] it's kind of old skool, chopping up one vocal and turning it into a whole dance track.".
Nick Levine of Digital Spy gave the song four out of five stars and wrote: "'One (Your Name)' is a booming Eurodance club banger boasting an ear-snaggingly simple synth line, trancey whooshes aplenty and cred-boosting vocals from Neptunes star Pharrell Williams [...] it's neither original nor refined, but boy does it hit the spot."
Videos were made for both the Pharrell Williams and the instrumental Version, with little differences. The videos follow the night of an unidentified woman playing a Teenage Engineering OP-1 digital synthesizer at a party. The video depicts various characters—fire breathers, dancers, bodybuilders, and masked people. There is heavy use of alcohol and what appears to be laughing gas, a common recreational drug, as well as graphic sex and violence scenes. A masked man (hypothesized to be David Guetta, given the tattoo on the character's arm reading "F*** ME, IM FAMOUS", the name of Guetta's mix albums) assaults the main character. This could be interpreted as a dig at David Guetta, who people believe plagiarized elements of "One" in his song, "50 Degrees". The video currently has over 40 million views on YouTube. This song is sampled in "All Star" by Tydolla$ign, featuring Joe Moses and Swedish House Mafia.
The music video was directed by the Swedish directors Henrik Hanson and Christian Larson who both have worked for the renown Swedish director Jonas Åkerlund. Hanson, who started his career for Åkerlund at only the age of 15, is now one of the most successfully established young Swedish directors. In 2009 Hanson and Larson directed the documentary film Take One about the Swedish House Mafia.
