Question: Who produced Lady Gaga's third studio album?
Context: Paul Blair (known by his stage name DJ White Shadow, sometimes written as DJWS) is an American music producer and DJ currently based in Chicago, Illinois.  He is best known as the producer for "Yu-Gi-Oh! " and Lady Gaga's "Born This Way" and "Artpop" albums.

It was written and produced by Gaga with French DJ Madeon, with additional writing credits from RedOne and Paul "DJ White Shadow" Blair.  The song was developed with Madeon after Gaga's Born This Way Ball tour performance in France.  "Gypsy" was described by Gaga as "Artpop"' s most personal song; she elaborated that it was about travelling the world and the loneliness associated with it.  A Europop and electropop song, "Gypsy" is a 1980s style "anthemic" track with piano and guitar instrumentation, and lyrically talks about Gaga's fans as being the people she feels closest to.  The track was mistakenly assumed to be the third single from the album when Interscope Records listed it on their SoundCloud page reserved for future releases. "Judas" is a song by American singer Lady Gaga, from her second studio album, "Born This Way" (2011).  It was released four days ahead of schedule by Interscope Records on April 15, 2011.  Written and produced by Lady Gaga and RedOne, "Judas" is a dance and electro house song about a woman in love with a man who betrayed her.  It embodies the incidents that have haunted Gaga in the past, and its core meaning refers to the negative parts of her life that she cannot escape.  Gaga has further explained that the song was also about honoring one's inner darkness in order to bring oneself into the light.  The artwork for the single was designed by Gaga in Microsoft Word.  In spite of a polarizing impact on several religious groups, the song was generally well received by critics, who likened the song to "Bad Romance" with some noting it should have been the album's lead single. ArtRave (stylized as artRAVE) was a two day event hosted by Lady Gaga from November 10–11, 2013, as part of the promotional campaign for her third studio album, "Artpop" (2013).  The event, held in a large warehouse in the Brooklyn Navy Yard in New York, served as an album release party and included a press conference and a live performance.  During the press conference, Gaga revealed "the world's first flying dress", called the Volantis, confirmed plans to stage a performance in space in 2015, and introduced new works by Marina Abramović, Inez van Lamsweerde and Vinoodh Matadin, Jeff Koons, and Robert Wilson.  The warehouse contained a giant statue of Gaga created by Koons on one side and other artworks, while screens all around displayed videos of Gaga's performances with Abramović.

"Applause" was inspired by the cheering of her fans, which kept her motivated during the months she toured with the Born This Way Ball in pain, before cancelling it due to a hip injury.  It is an electropop and Eurodance song built around synthesizers and hi-NRG beats, with lyrics addressing how Gaga is dependent upon her fan's adoration and how she lives to perform.

Artpop (stylized as ARTPOP) is the third studio album recorded by American singer Lady Gaga, released on November 6, 2013, by Streamline and Interscope Records.  Gaga began planning the project in 2011, shortly after the launch of her second effort, "Born This Way".  Work continued until 2013 while the singer was traveling for her Born This Way Ball concert tour and recovering from surgery for an injury she had sustained while touring.  Gaga described "Artpop" as "a celebration and a poetic musical journey" and an exploration of the "reverse Warholian" phenomenon in pop culture.  It displays an intentional "lack of maturity and responsibility" by comparison to the darker and anthemic nature of "Born This Way".  Gaga collaborated with various producers on the record, including Paul "DJ White Shadow" Blair, RedOne, Zedd and Madeon.  Lyrically, "Artpop" revolves around Gaga's personal views of fame, sex and self-empowerment; references include Greek and Roman mythology.  It also features guest vocals from T.I., Too Short, Twista, and R. Kelly. "Sexxx Dreams" (censored as "X Dreams") is a song by American singer Lady Gaga from her third studio album, "Artpop" (2013).

Inspired by Gaga's erotic fantasies and dreams, the song went through a number of changes to make it understandable for the singer's team, while keeping a constant chorus.  A synthpop song, Gaga promoted the title by using a number of hashtags involving the name in her social media accounts, and at one point was considered for a single release from "Artpop".

The song was released for promotion on Farmville, six days before the release of "Born This Way".
