"Pa' Ti" was written by the duo alongside Andrea Mangiamarchi "Elena Rose", Jon Leone and Edgar Barrera and produced by the former two.

The eight-minute-long, double music video received praise for its cinematic nature, and drew comparisons to the films Chicago and The Wolf of Wall Street.

While promoting her single "Medicine" in April 2019, Lopez told Ebro Darden of Beats 1 radio that the next album she releases will "probably be with a new movie".

[4] During their first week of shooting, on October 5, 2019, Lopez and Maluma performed her song "No Me Ames" during his show at Madison Square Garden in New York City.

[14][1] Jon Caramanica of The New York Times described the collaboration as "A pair of effective new songs from Jennifer Lopez and Maluma, well-matched singers more interested in rhythm than power, more invested in melodrama than depth.

[1] Also writing for Billboard, Jason Lipshutz stated, "The vocal chemistry is palpable on both tracks, as Lopez eases her approach to match Maluma’s more hushed romance; if the pair combines for a longer collaboration, it would be one to remember.

[11] The eight-minute video begins with a brief interlude, showing scenes of New York, while various media and news outlets can be heard describing "corruption on Wall Street" and mysterious financial crimes being committed.

Lopez sings about her lavish lifestyle as Maluma opens the door to her car and transports her to her office, which was filmed on the hundredth floor of The Edge at 30 Hudson Yards.

[11] Writing for Harper's Bazaar, Chelsey Sanchez described the video for "Pa' Ti + Lonely" as a "cinematic narrative (think The Wolf of Wall Street meets Chicago)", and also regarded it as having "some of the hottest fashion moments to grace our laptop screens this year.

[14] Mike Wass of the website Idolator stated that the video "seems to have a bigger budget than most independent movies", calling it a "serve from beginning to end".

"[13] Gabriela Arevalo of Radio.com stated that "audiences are taken on an emotional rollercoaster" throughout the two-part video, calling it "a story full of intrigue, suspense, and further proof that Lopez’s dancing skills in Hustlers were just a taste of what the former fly girl can do.

"[26] Lopez and Maluma performed both the songs live for the first time during the American Music Awards of 2020, at the Microsoft Theater in Los Angeles on November 22, 2020.

[27] Upon the premiere of the video through TikTok, Lopez had invited the application's two biggest stars Charli D'Amelio and Addison Rae to start a promotional dance challenge for "Pa' Ti" on the platform.

[29] As part of the challenge, Lopez and TikTok partnered with the yogurt company Yoplait, where the latter agreed to donate $1 to Feeding America for every "#PaTiChallenge" and "#YoplaitimeDonation" hashtag shared until October 30, 2020.
