I feel like this is promoting a perfume, or an autobiography, or something.

Katherine St Asaph: The Donna Summer quote was the label’s one indulgence; otherwise, the chorus would go “I want to top the dance charts again.” If that happens, Pitbull will roll out sesame-infused vodka. You know what to do.

Anthony Easton: There are a number of metaphors here that strike me as icky, including but not limited to J.Lo calling herself a big girl, and Pitbull suggesting that his skills at dancing will make it easier for him to open her “treasure chest,” which I think is her vulva.

Iain Mew: I find it charming how much the chorus sounds like Jennifer is making it up as she’s going along, trying to answer a question and running out of ideas (“Dance! Love! Er… I give up… ooh! Dance again!”). The melody there helps a lot. There is nothing else good to say about the song, though, and Pitbull is far too much of a blight for it to survive intact.

Alfred Soto: With Pitbull grunting and winking as if setting out to prove his presence was ancillary, the Woman Formerly Known As Jennifer Lopez steps lightly around canned electrobeats and lets the facets of her diamonds gleam with the density and repelling powers which have never been hers. Still, she remains ambitious: she’s determined to make “Waiting For Tonight” and “Control Myself” exceptions.

Brad Shoup: I love her melody, maybe more so than anything since “Waiting For Tonight”. It’s almost psychedelic in its disco indulgence. The double-tracking — implemented for obvious reasons — really puts things over here. Still, I have absolutely no idea why Pitbull gets another go-round. Perhaps this was recorded around the time of “On the Floor,” and Lopez thought her comeback was tethered to his goonish charisma. His highlight here is taunting a dude whose girlfriend has chosen monogamy or something.

Edward Okulicz: For a pop star as good as J.Lo is famous, “Dance Again” would be considered tedious and formulaic. For J.Lo herself, its obviousness, adherence to convention and inoffensiveness are about all it has going for it. Pitbull’s blathering makes it sound like even he thinks he’s overexposed, and yet, he won’t shut up.
