Question: What element of Christina Aguilera's "Red Hot Kinda Love" makes it a hip hop track?
Context: "U and Dat" is the second single from E-40's album "My Ghetto Report Card".  The song features American singers T-Pain and Kandi Burruss, and it was produced by Lil Jon.  A remix was released in early August with Juelz Santana, Snoop Dogg, and Lil' Flip.  It was featured on an Amp'd mobile commercial.  Although it is considered a West coast hip hop song, the song's beat structure incorporates typical southern hip hop snares as well as Lil Jon's signature crunk synths and whistles.  The catchy, up-tempo and club oriented southern hip hop track allowed the song to peak at #13 of the U.S. Billboard Hot 100.  The track is credited to have popularized the use of T-Pain as a hook singer on hip hop tracks.  The song was certified platinum by the RIAA on March 31, 2016. "Castle Walls" is a song by American singers T.I. and Christina Aguilera, from T.I.'s seventh studio album "No Mercy" (2010).  Alex da Kid produced the song and co-wrote it along with Skylar Grey and T.I.  The song was initially produced for Diddy's album "Last Train to Paris", but Diddy felt that "Castle Walls" would be better suited to T.I.; Aguilera was later chosen as the featured artist on the song.  A hip hop and electro number, "Castle Walls" received mixed response from music critics, some of whom picked it as a highlight from "No Mercy", and some others criticized the song's lyrics.  Despite not being released as a single, the track still managed to appear on record charts of several nations, including on the US Bubbling Under Hot 100 Singles, where it peaked at number five. Mad as a Hatter is the debut EP by Australian hip hop group Def Wish Cast.  It was released in 1992 on vinyl by Random Records.  All production and turntablism is by DJ Vame, except "Proppa Ragga", which was produced by DJ Sing.  "Proppa Ragga" was the first Australian hip hop track to receive international recognition, albeit at Norway, coming in at number 2 on its NRK's Hip Hop show (hosted by Tommy Tee).  In 2007, a copy of "Mad as a Hatter" sold on eBay to a German bidder for more than A$430.  The EP samples Walt Disney's "Alice in Wonderland" in the title track. "Can't Stop, Won't Stop" is an American Grammy-nominated song performed by American hip hop duo Young Gunz, as members of Philadelphia hip hop group State Property.  A remix version appeared on the Young Gunz' debut album "Tough Luv", featuring Chingy, and was also featured on The Roots live album "The Present".  It became a major hit and the highest charting State Property song to come out of the group.  Its catchy, up-tempo and club oriented east coast hip hop track allowed the song to peak at #14 on the U.S. "Billboard" Hot 100. Stripped is the fourth studio album by American singer Christina Aguilera.  It was released on October 22, 2002 by RCA Records.  Looking to transition from the teen pop styles of her self-titled debut album (1999), Aguilera took creative control over her next album project, both musically and lyrically.  She also changed her public image and established her new alter ego, "Xtina".  Musically, its music incorporates pop and R&B with influences from many different genres, including soul, metal, rock, hip hop, gospel and Latin music.  Lyrically, most of the songs from the album discuss the theme of self-respect, while a few other songs talk about sex and feminism.  As executive producer, Aguilera enlisted many new collaborators for the album. "Dirrty" is a song recorded by American singers Christina Aguilera and Redman for the former's fourth studio album "Stripped" (2002).  Despite Aguilera's first three years of commercial success, she was displeased with the lack of control over her image.  In response, she desired to create a song that would represent her authentic persona.  She approached hip hop producer Rockwilder and suggested using Redman's 2001 song "Let's Get Dirty (I Can't Get in da Club)" as a guide.  The final result, "Dirrty", is an R&B and hip hop song that also features rapping verses from Redman.  The song is about sexual activities. "Red Hot Kinda Love" is a song by American recording artist Christina Aguilera from her seventh studio album, "Lotus" (2012).  The song was written by Aguilera, Lucas Secon and Olivia Waithe, with production done by Secon.  It is a multi-genre song, combining dance, disco, hip hop, Latin and pop.  The track makes use of two samples: "The Whole Wide World Ain't Nothin' But a Party" performed by Mark Radice and "54-46 That's My Number" performed by Toots & the Maytals.  Lyrically, the song talks about Aguilera's attempts to impress the man she is flirting with and she will not go home without him.  Its structure received comparisons to songs performed by Britney Spears and Kylie Minogue.  The track was received positively by critics, the majority of whom praised the fun and playful production.  Upon the release of "Lotus", the song debuted at number five on the South Korean international singles chart, selling 20,433 copies, and remained on the chart for a further four weeks. "Elastic Love" is a song recorded by American recording artist Christina Aguilera, taken from her sixth studio album, "Bionic" (2010).  The song was written by Aguilera, M.I.A., John Hill and Switch, while production was handled by the latter two.  Originally, "Elastic Love" was recorded by M.I.A., but later it was given to Aguilera.  However, M.I.A. was disappointed when Aguilera didn't want to do her "trademark warbling" in the studio.  "Elastic Love" is an electro and electropop song with strong elements from 1980s new wave music.  Lyrically, Aguilera compares her love to office supplies, from paperclips to rubber-bands. Hip hop music, also called hip-hop or rap music, is a music genre developed in the United States by inner-city African Americans in the 1970s which consists of a stylized rhythmic music that commonly accompanies rapping, a rhythmic and rhyming speech that is chanted.  It developed as part of hip hop culture, a subculture defined by four key stylistic elements: MCing/rapping, DJing/scratching with turntables, break dancing, and graffiti writing.  Other elements include sampling beats or bass lines from records (or synthesized beats and sounds), and rhythmic beatboxing.  While often used to refer solely to rapping, "hip hop" more properly denotes the practice of the entire subculture.  The term "hip hop music" is sometimes used synonymously with the term "rap music", though rapping is not a required component of hip hop music; the genre may also incorporate other elements of hip hop culture, including DJing, turntablism, scratching, beatboxing, and instrumental tracks. "Can't Hold Us Down" is a song recorded by American singer Christina Aguilera and rapper Lil' Kim for the former's fourth studio album "Stripped" (2002).  It was released by RCA Records on July 8, 2003, as the fourth single from the album.  The track was written and produced by Scott Storch, with additional songwriting by Aguilera and Matt Morris.  An R&B and hip hop song with dancehall elements, "Can't Hold Us Down" criticizes gender-related double standards.
