It also features vocals from Colby O'Donis and was released on April 8, 2008, as the lead single from Gaga's debut studio album, The Fame.

"Just Dance" received acclaim from music critics, who complimented its club anthem-like nature and the sound associated with it.

The song was a sleeper hit, spending almost five months on the Billboard Hot 100 before finally peaking at the chart's summit in January 2009.

Its music video portrayed Gaga appearing in a party where she plays the song, prompting party-goers to start dancing in enjoyment.

"[4] In an interview with Contactmusic.com, Gaga explained that "Just Dance" is a happy record and is supposed to be appreciated by people going through rough times like losing jobs and homes etc.

Being asked the reason for which "Just Dance" has become popular, Gaga said that she thought, "Everyone is looking for a song that really speaks to the joy in our souls and in our hearts and having a good time.

"[6] In March 2010, the song was released as downloadable content for the music-based videogame series Rock Band, alongside "Poker Face", "Monster" and "Bad Romance" as part of "Lady Gaga Pack 01".

[9] "Just Dance" is an uptempo electropop,[10][11] synth-pop[12][13] and dance-pop[14][15] song, combining synths of clipped marching beats with soaring electronics.

[21] Alexis Petridis of The Guardian called it a "beguilingly compulsive tale of pulling a drug-induced whitey, with a combination of clipped marching beats, sawing electronics and mild R&B flavor that bears a vague resemblance to Nelly Furtado's 'Maneater'".

[17] Ben Norman of About.com said that the song "opens the album like a valkyrie leading the charge [...] riding triumphant ahead of her army.

He also added that "'Just Dance' has strong energy and features Lady Gaga's striking voice, but it ultimately adds up to rather bland dance-pop".

[24] Ben Hogwood of MusicOMH praised the song saying, "You won't get many more catchy party odes than the chart topping Just Dance this year, a polished gem set to lodge in your head for the next few weeks".

[26] Lynn Saxberg from the Ottawa Citizen, while reviewing Gaga's The Fame Ball Tour, called the song a perfect sing-along club anthem.

[27] Sal Cinquemani from Slant Magazine wrote that the song resembles the "desperate train wreck you're likely to encounter getting wasted at any dive on the L.E.S.

[36] It was the second song to reach the six-million mark in paid downloads, following "I Gotta Feeling" by The Black Eyed Peas.

[41] The song was certified six times platinum by the Canadian Recording Industry Association (CRIA) in June 2009, for sales of 240,000 copies in paid digital downloads.

[43] "Just Dance" was certified twelve times platinum by the Australian Recording Industry Association (ARIA) for shipment of 840,000 copies.

[46] It has been certified quadruple platinum by the Recording Industry Association of New Zealand (RIANZ) for shipment of 120,000 copies of the single.

[48][49] Gaga explained her feelings on reaching number-one in the United Kingdom saying, "It's been a long running dream to have a big hit in the UK – my fans there are so sexy and the people are so innovative and free in how they think about pop culture and music.

[53] By January 2017, it had been streamed 6.3 million times in the nation according to the Official Charts Company,[54] and by May 2020 the song had sold 968,000 copies.

Gaga denied it and released a statement saying "I was sick the day of the show but I absolutely, 100 per cent, was singing live.

Her dancers were clad in Louis Vuitton Steven Sprouse printed trousers which matched Gaga's shoes.

The backdrop changed to show blinking disco lights and Gaga stood wearing her video sunglasses, displaying the line "Pop Music Will Never Be Low Brow".

Emily Zemler from The Hollywood Reporter noted that "For all her preconceived speeches, these genuine moments resonated deeply with the audience, most of whom were dressed in tribute to the singer.

[83] For her worldwide tour, ArtRave: The Artpop Ball, Gaga combined "Just Dance" with short performances of "Poker Face" and "Telephone".

While she danced and sang the songs, the backdrops displayed multiple images of Gaga writhing around, while wrapped in tinsel and moss.

[85] Melissa Ruggieri from The Atlanta Journal-Constitution was impressed with Gaga's vocals and complimented her for performing "old songs" in her actual voice.

[90] On the Joanne World Tour (2017–2018), Gaga wore a pearl-encrusted pale blue bodysuit with dramatic shoulder pads, and knee-high lace up boots while performing the track.

[94] "Just Dance" was featured in an episode of The Office by the name of "Michael Scott Paper Company", in which Steve Carell's character mistakes it for a Britney Spears song.

The song was also planned to be on the main track list of the video game Just Dance 2, but it was scrapped for unknown reasons.
