|Katy Perry singles chronology|
"Birthday" is a disco song recorded by American singer Katy Perry for her fourth studio album, Prism (2013). She co-wrote the song with Bonnie McKee and its producers Dr. Luke, Max Martin, and Cirkut. Critics, as well as Perry herself, have compared the track to the music of Prince and Mariah Carey. Through double entendres in the lyrics of "Birthday", Perry makes sexual references while celebrating a partner's birthday. Capitol Records sent the track to mainstream and rhythmic radio on April 21, 2014 as the album's fourth single.
Following the release of Prism, "Birthday" entered the single charts of South Korea and France. After being released as an official single, it reached the top 30 in Australia, UK, and Netherlands, number 17 on the US Billboard Hot 100, and number 7 on the Canadian Hot 100. A music video for the track was released on April 24, 2014. Primarily recorded with hidden cameras, it features Perry disguised as five different characters in birthday parties and other celebrations. The makeup effects disguises for Perry were designed and created by Tony Gardner. Jess Glynne covered the song on BBC Radio 1's Live Lounge, and Halsey on SiriusXM.

Production and release
"Birthday" was written by Perry, Bonnie McKee, Cirkut, Dr. Luke, and Max Martin. The latter three produced the song and contributed to the instrumentation and programmed their respective instruments. The drums were played by Steven Wolf, while the horns were played by the Saturday Night Live Band, arranged by Lenny Pickett and engineered by Dave O'Donnell. Its audio engineering was done by Peter Carlsson, Clint Gibbs, Sam Holland, and Michael Illbert. The track was finally mixed by Serban Ghenea at the MixStar Studios in Virginia Beach, Virginia, accompanied by the mixing engineer, John Hanes. The song itself was recorded at various studios, including Luke's in the Boo in Malibu, California, Conway Recording Studios in Hollywood, California, Playback Recording Studio in Santa Barbara, California, MXM Studios in Stockholm, Sweden and Secret Garden Studios in Montecito, California.
The song surfaced online on October 16, 2013—two days prior to the official release of Prism. On April 3, 2014, the singer announced on her Twitter account that "Birthday" would be released as the album's fourth single, posting its cover art as well. The art is based on a photograph, taken during a birthday party circa 1990, in which a blonde Perry and her sister Angela Hudson smile toward the camera; "puffy" letter balloons were "photoshopped" onto the cover to spell out Perry's name. The song title appears in candles over a floral cake. To promote the single, a lyric video for "Birthday" was uploaded onto Perry's Vevo account on April 10, 2014. It depicts a variety of cakes and sweets—among other confections—decorated with the song's lyrics and concludes with Perry lighting the last candle of a cake.
At the length of three minutes and thirty-five seconds (3:35), "Birthday" is primarily styled in the genre of disco. "Birthday" is composed in the key of B major and follows a progression of Emaj9–C♯m7–Emaj9–C♯m7–B with a tempo of 126 beats per minute. Perry's vocals range from B3 to F♯5. During a preview event for Prism, held in New York City, Perry described "Birthday" as her "attempt at writing" a song that American singer and songwriter Mariah Carey would have included in her eponymous debut album. Since its release, its musical composition has been strongly compared to that of other works of Prince and duo Wendy and Lisa.
"Birthday" contains elements of funk-pop, synthpop, and disco house. The song is backed by a "busy but buoyant" instrumentation featuring a "deeply rhythmic impulse". Randall Roberts of the Los Angeles Times felt "Birthday" was a musically updated version of disco, achieved by replacing "cheesy strings" with "jerky breaks and synth washes". Its "joyful" lyrics present the commemoration of her partner's birthday as a metaphor for sexual intercourse. The bridge section of "Birthday", which sees Perry singing "Let me get you in your birthday suit / It's time to bring out the big balloons", was found by Ben Rattliff to resemble French duo Daft Punk's works.
AllMusic's Stephen Thomas Erlewine and Kitty Empire from The Guardian called "Birthday" one of the best tracks from Prism: Erlewine described it as a "glorious retro-disco explosion" and Empire found a "girly simpatico" in the song that sustains it. Marah Eakin from The A.V. Club felt the track was "pure fun". Jason Lipshutz of Billboard called it a "stone-cold stunner", going on to say the song "serves as pop music's (superior) answer to Swizz Beatz's "Everyday Birthday". He also felt it was the song with the "most smash potential" included in Prism. Chris Bosman of Consequence of Sound wrote that the song was a "irrepressible disco jam" and found it superior to Carly Rae Jepsen's album Kiss (2012).
Jon Dolan from Rolling Stone noted that the "sunny effervescence" from Teenage Dream was present on the song. Sal Cinquemani from Slant Magazine said that the "sexy and playful" song was "offset by brackish fare". Alexis Petridis from The Guardian considered that the song resembled a four to the floor remix of a Mariah Carey song, but complimented its melodies for being "significantly stronger" than those of Jessie J's album, Alive (2013). Rob Harvilla from Spin criticized the song's "sensuality", which he described as being of "an off-kilter, grade-school goofy, beanie-propeller sort of sensuality". Evan Sawdey of PopMatters deemed "Birthday" the "catchiest thing" on Prism, but he also thought it was a "rewrite" of Jessie J's hit "Domino" and Perry's former song "Last Friday Night (T.G.I.F.)". Lewis Corner from Digital Spy classified it as a "flirty pop-gem", while HitFix's Melinda Newman awarded it a B+ grade, calling it a "delectable pop confection". James Reed from The Boston Globe called the song's double entendre lyrics "hilarious".
Upon the release of Prism, due to strong digital download sales, "Birthday" charted on the singles charts in France and South Korea. It debuted on the Syndicat National de l'Édition Phonographique singles chart at number 160 where it stayed for one week. In South Korea, it peaked at number 51 on the Gaon International Chart with digital downloads of 3,089 copies. Before being released as a single, the song debuted on the Billboard Hot 100 chart of April 16, 2014, at number 91. One week later, the song jumped to number 83. The following week, it went from 83 to 37. It peaked at 17 on the Hot 100. The song has peaked at the top of Hot Dance Club Songs chart extending her record for most consecutive dance club no.1 songs to 14.
Development and filming
The official music video for "Birthday" was directed by Marc Klasfeld and Danny Lockwood; Dawn Rose served as a producer, while Nicole Acacio served as executive producer, Richard Alarcón served as the editor, Tony Gardner as the make-up artist, and Joseph Robbins was the director of photography. For the video, which was filmed in April 2014, Perry played the characters of five party entertainers, appearing in five parties. They consisted of a burlesque-like elderly woman named Goldie, a Jewish master of ceremonies named Yosef Shulem, a clown named Kriss, an animal trainer named Ace, and a face-painter named Princess Mandee. In order to transform physically into each character, Perry spent up to seven hours getting prosthetic makeup applied by Tony Gardner.
The parties that Perry attended were real, and its participants were unaware of Perry's presence; the organizers believed they had signed up to star in a reality show called "Birthday Blowouts". Similarly, the majority of events that took place during the visual were staged without the knowledge of the celebrations' organizers and guests. For example, the car crash that occurs in the video left several children who observed it frightened and crying. Perry deemed the video "very intricate to make and shoot" and her "most insane" to date. A teaser for the video which introduced the characters was released on April 22, 2014 whereas the complete video was revealed two days later.
The music video begins with short introductions to the characters Goldie, Yosef, Kriss, Ace, and Mandee. Perry is then shown entering all of the parties as "five of the world’s worst birthday entertainers" in disguise. At a man's 90th birthday, Goldie emerges from a large birthday cake and begins to give the man a lap dance. At a child's birthday party, Kriss the Clown attempts to create balloon animals, while Ace the Animal Trainer introduces a group of children to a box of mice before appearing to eat one, which makes a child cry. At another child's party, Princess Mandee paints a girl's face incompetently; Goldie begins to suffer from respiratory problems, and Yosef does the worm at a boy's Bar Mitzvah. Goldie pulls a man's prosthetic leg off and proceeds to play air guitar with it, and Kriss crashes into a table before drinking alcohol behind a tree.
At the elderly man's party, Goldie collapses and a woman tries to use a defibrillator on her. While attempting to hit a piñata, Kriss walks onto the road to cause a car crash which shocks the party attendees. At the petting cage, Ace lets a goat run wild which defecates and urinates on the ground; meanwhile Goldie drops a birthday cake on the 90-year-old man, Yosef is then shown beatboxing at the Bar Mitzvah to the disapproval of the guests. Princess Mandee takes off her hat, wig and mask and reveals herself to be Perry, to which the children scream in pleasure. Goldie eats cake with the elderly man, before straddling him on his wheelchair. At the end of the song, Princess Mandee and the children say "happy birthday" to the camera. During the credits, the characters dance and lip sync to a remixed version of the song.
Christina Garibaldi of MTV News wrote that Perry "continues to top herself" with the video and billed the video's "approach" as "creative, fun and pretty hysterical". Salon's Daniel D'Addario was critical of character Yosef Shulem, denouncing it as a "Jewish stereotype". He noted that Perry had already been the center of controversy due to being dressed as a geisha for a 2013 performance of "Unconditionally", and questioned her decision to portray Yosef. Writing for Time, Nolan Feeman quipped, "Jewish people aren't costumes" and found the video distracting from the song. Ariana Bacle from Entertainment Weekly dubbed the character "anti-Semitic" and suggested that Perry should stop impersonating members of other cultures. For Consequence of Sound, Chris Coplan called the visual "incredible" and described it as a "less grating and tiresome" version of The Master of Disguise. Complex writer Zach Frydenlund positively remarked that the video "deliver[ed]" and regarded the Goldie character look as "quite nice".
