作词与灵感.
《舞力全开》起初由卡卡与阿肯与歌曲的制作人RedOne合作作词。在杂志《》的采访中，卡卡解释这首歌的作词灵感。她说:「当时我身陷酒醉。我花了10分钟与RedOne一起作词，这是我第一次在好莱坞录音室里工作。感觉颇新鲜的，待在这样一个装有巨大扬声器的巨大房间中。」 卡卡于2008年1月为《舞力全开》作词，她表示这作品「投入了大量心血，而最初，有一大群人认为这不会成功。」 之后卡卡表示：
「这首歌拯救了我。我过去曾深陷在纽约黑暗的一面中，我曾如此郁闷并整天泡在酒吧中。我坐上飞机前往洛杉矶去制作我的音乐并一次性的试著写出一首足以改变我人生的歌，而我做到了。从此我再也没有回去，我放下了我的男友，我的公寓套房。不再回头。而我的母亲为我亲身打理了这些事。」
在的采访中，卡卡解释《舞力全开》是首快乐的歌曲并用于鼓励历经人生低潮: 例如失去工作或房子等等的人。 她曾进一步与解释她希望以《舞力全开》写出一首美丽的歌。当被问到为何《舞力全开》如此出名时，卡卡表示她认为「每个人都在寻找著能够完全表达我们灵魂和心中的喜悦并享受美好时光的歌曲，而这首歌就是其中之一。这首歌感觉真的很棒，而当你听下去时，它也会使你的内心也感到雀跃。它就是这么简单。我认为这首歌能够直达心房并不是什么难事。因为它是以心灵为主题的歌曲。」 2010年3月，《舞力全开》与《扑克脸》、《》、《罗曼死》作为节奏电子系列游戏《》的下载包「Lady Gaga Pack 01」。
创作与构思.
《舞力全开》是一首有节奏感的合成器流行和流行舞曲类歌曲。歌曲结合了带有轻快节拍的合成乐，并在提升了电音部份的同时加入了当代节奏蓝调的鼓舞性节奏。 歌曲制作时音调以升C小调为主并加入了每分119拍的适度舞蹈节奏。卡卡的声域跨度于最低G3至最高C5。 歌曲在卡卡在合成乐带起的轻快节奏下喊出「RedOne」时开始。《舞力全开》有著 Cm–E–B–Fm的基本和弦进行。 在歌曲中，奥多尼斯以跟卡卡相同的声域演唱， 接著是卡卡带有节奏蓝调风格的桥段， 之后，在奥多尼斯担任和声并提供行进节奏时重复唱出副歌。并在字词「dance」的回音下结束。
就歌词上，《舞力全开》以歌词「舞池里发生了什么? / 我爱这旋律，宝贝，但我已经无法直走」 带出不完全的诙谐视角。 歌词整体描述在派对中完全的酒精中毒。 歌曲开头的歌词「A RedOne」时常被误听为「red wine」但这段时是影射到歌曲制作人RedOne。
评论反响.
Matthew Chisling of AllMusic described the song as "a powerhouse of dance waves and infectiously produced beats". 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'". Ben Norman of About.com said that the song "opens the album like a valkyrie leading the charge [...] riding triumphant ahead of her army. If you don't know this song, use your browser. I won't waste time explaining what it sounds like." However he also noted that the song is not groundbreaking and compared it to the music of Rihanna, Chris Brown and The Pussycat Dolls. Bill Lamb from About.com called the song tame but catchy enough for Gaga to be noticed by mainstream. 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." O'Donis' smooth vocals were also complimented.
Evan Sawdey of "PopMatters" said that "Just Dance" is an intensely catchy single and is an excellent indicator of what the album was all about. 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." Freedom lu Lac of "The Washington Post" described the song to be "filled with mindlessly frothy synth-pop that matches low-grade dance grooves with GaGa's icy, almost disembodied vocals about dancing bliss". Lynn Saxberg from the "Ottawa Citizen", while reviewing Gaga's The Fame Ball Tour, called the song a perfect sing-along club anthem. 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. at four in the morning" as is emphasized by the lyrics. Talia Kranes from BBC called the song irresistible and said that "the catchiness of her songs is sure to cement her place in the list of pop idols".
