[1] Additionally, "Rain on Me" topped the charts in Canada, Croatia, Greece, Hungary, Ireland, Israel, Scotland, Singapore, and the United Kingdom.

The accompanying music video was directed by filmmaker Robert Rodriguez, and features Gaga and Grande dancing inside a giant arena during a rainstorm, with daggers falling from the sky.

[3] Gaga disclosed that she had collaborated with a "fellow female pop star who [had similarly experienced] immense trauma while in the public eye" and went into depth about the genesis of their song: "I sat with her and we talked about our lives.

In her May 21, 2020 interview with Zane Lowe on Apple Music's Beats 1, Gaga further talked about the writing process of the song:[Grande] was so wonderful and I think that maybe she assumed that she was gonna come in and I would be like "here, just sing this and thank you so much for your time" right.

[4]"Rain on Me" was written by Gaga, Grande, Burns, Nija Charles, Rami Yacoub, Bresso, Boys Noize and Chromatica executive producer BloodPop.

[5][6] Co-producer Burns explained that he wanted to create the "same energy" that songs like "Another Chance" by Roger Sanchez and "Music Sounds Better with You" by the French house group Stardust have, so that it could "feel classic but modern at the same time.

[32] To coincide with the single release, rain-themed merchandise items were made available in Gaga's official online store, such as rainboots, ponchos, and umbrellas.

[37] On August 26, 2020, Gaga announced an online competition with a $10,000 cash grand prize for the winner, where participants had to design a poster inspired by "Rain on Me", using Adobe creative apps.

An "emote" titled "Rain Check" was added to game's shop that prompts a player's character to "perform" a portion of the track's official choreography in-game.

"[23] Dave Quinn from People highlighted "Grande touching her signature high note octaves" and "Gaga's bold voice" that "echos throughout the track as she sings, "Rain on Me" and "Hands up to the sky/I'll be your galaxy".

"[9] In a rave review, Brenden Wetmore of Paper described the song as "absolutely electric by its end, having charged up enough raw emotion and heartbreak to power an entire circuit party's worth of strobe lights.

"[20] Craig Jenkins of Vulture complimented the singers' vocals and the beat, and thought that the song "will be huge", because "it has that nebulous quality memorable pop hits have where the lyric seems distinctly about one thing but also not about anything in particular.

He also thought that "it's the release all of us have needed at least a couple dozen times during this pandemic", while highlighting its uplifting message: "No matter how bad the storm gets, we will endure and perhaps come out a little cleaner on the other side for the pain.

[51] Evan Sawdey from PopMatters named it "one of [Gaga's] all-time greatest singles", that "flies through its three-minute run time so quickly you barely realize it's about alcohol abuse".

[54] Chris DeVille from Stereogum named "Rain on Me" as the best pop song of 2020, calling it an epic dance track that finds euphoria in resilience and stating "Over a mammoth '90s-vintage house beat, Gaga and Grande channeled every ounce of their diva power, not quite erasing their trauma and struggle but vanquishing it for three minutes at a time".

[55] Helen Ainsley from the Official Charts Company picked "Rain on Me" as her favorite song of 2020, stating that "like a sudden downpour after a heatwave, 'Rain on Me' was an antidote to the drudge and uncertainty of the first few months of lockdown.

This candid collab between two of pop's most beloved powerhouses was a rousing reminder that while we may be struggling, at least we're alive, packaged inside a dance-pop stomper that would have dominated clubs had they been open.

The song's sales were aided by four physical/digital combination offerings during the tracking week; consumers could also purchase cassette, CD, and vinyl singles, each with a digital download.

[72] In Canada, "Rain on Me" entered the Canadian Hot 100 chart at the top position on the issue dated June 6, 2020, becoming Gaga's sixth and Grande's fourth number one single in the country.

[78] Laura Pulice designed the outfits that Gaga and Grande were wearing, and Vex Clothing, a business that specializes in latex suits, made them.

"[78] The singers' makeup was done by Sarah Tanno, who used products from Haus Laboratories and "wanted the looks to feel powerful, pop, with a mix of dangerous rebellion.

He added that he really enjoyed the process because he was "able to work with both Gaga and Ariana and design their dances based on their individual artistic personalities, unique likenesses and differences, as well as how they each sang their lyrics.

[84] On August 6, 2020, Gaga released the forty-eighth episode of her web series Gagavision, showing her and Grande going through rehearsals and filming the music video.

[82] The video also features "some dramatic close-ups of Gaga with rain pouring down her face" behind a pane of glass and a scene where the two singers are holding hands, "each with lengthy Sailor Moon hair floating in the wind behind them".

Amy Mackelden of Harper's Bazaar thought the music video "is nothing short of iconic", and "features dramatic costume changes, and killer dance moves".

[90] Erin Vanderhoof of Vanity Fair called it a "lavishly produced and animated video" with "TikTok–friendly" dance moves, and found it "a bit of nostalgia to [...] the pre-coronavirus days".

[85] Kyle Munzenrieder of W magazine also noted that the choreography would translate well to TikTok videos as "the singers mostly stay static in place and pull the kind of moves one could easily record themselves doing in their bedroom".

[97] The show in Los Angeles, which was recorded for Gaga Chromatica Ball, involved fireworks exploding over Dodger Stadium during the closing part of "Rain on Me".

[101] Her rendition samples the songs "Time" and "Mequetrefe" off her fourth studio album Kick I (2020), as well as the Changa tuki track "Mételo Sácalo" by DJ Yirvin.

"[103] It also earned the praise of Pitchfork's Jamieson Cox, who thought it was Dawn of Chromatica's "most radical cut" that "situate[s] Gaga and Ariana Grande within Kick I's gossamer avant-pop.
