"I Bet You Look Good on the Dancefloor" is a song by English rock band Arctic Monkeys released on 17 October 2005 through Domino Recording Company.

Mike Smith, who signed them to EMI Publishing, claimed that with the release of this song, “Arctic Monkeys created a model that’s absolutely dominant today, The fact that you’re clicking on music to listen to as you did with them – they heralded what we’ve come to live in now.”[7] The song was recorded three times with different producers, the first version with Alan Smyth, and another with James Ford and Rich Costey, before landing on Abiss' version.

[8] The single cover features a young girl, wearing a trainee badge, working the cash register at a supermarket, and has the song title and the name of the band, overimposed in white inside of two black rectangles.

The way their early songs were distributed ushered in a new way of releasing music, In 2004 iTunes had launched in the UK and accounted for 17.9% of that year’s singles chart but by 2005, that number had more than doubled to 36.6%, with the band as a starting point.

Talent booker Alison Howe said, the week of the single release "felt like a moment that a generation would remember for the rest of their lives.”[7] In February 2008, Alan Wilder, former member of Depeche Mode, criticised the mastering of the song in an open letter on the Side-Line Magazine website.

On 27 July 2012, once the athletes had gathered in the centre of the stadium, the band performed the song and a cover of The Beatles' "Come Together" at the 2012 Summer Olympics opening ceremony.

"[21] Ben Thompson of The Observer praised Berrabah's "bluesy rasp" as a novelty,[22] while Jimmy Draper of Time Out wrote: "It transforms the punky rave-up into a disco stomper that could make even the staunchiest pop-hater get up and dance.

[30] Jayson Greene of Pitchfork was positive towards the cover, and thought the band found, "an easy slinkiness in the groove that feels right for Alex Turner's sidelong, cutting observations.
