 Jonah Weiner of Slate Magazine gave the song a negative review saying that "the song sets up ship on the fault line between charmingly daft and deeply irritating." He then compared the song to work by other artists, stating that "the rapped verses are sub-Fergie-grade, proudly stuffed with groaners and to-hell-with-the-expiration-date slang." Weiner echoed the sentiment that the plotline seemed like "a sequel" to "Just Dance", summing it up as "girl wakes up drunk, stays drunk, finds a dance floor and (spoiler alert) gets even drunker." Jon Caramanica of The New York Times described the song as "a zippy and salacious celebration of late nights and mornings-after." He noted that "some have compared Kesha, unfavorably, to Uffie, who is signed to the influential French electronic music label Ed Banger and whose sass-rap predated Kesha ’ s by a couple of years." However, he thought that "if anyone should feel fleeced by 'Tik Tok', though, it ’ s Lady Gaga, who probably hears significant chunks of her hit 'Just Dance' in its melody and subject matter."
