舞力全開 (歌曲)

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'".[8] 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.[14] 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.[15]

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.[16] 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."[17] 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".[18] Lynn Saxberg from the Ottawa Citizen, while reviewing Gaga's The Fame Ball Tour, called the song a perfect sing-along club anthem.[19] 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.[20] 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".[21]
