 He collaborated with rapper and producer Kanye West on the albums "808s & Heartbreak", "My Beautiful Dark Twisted Fantasy", and "Watch the Throne".

"Party" is a song recorded by American singer Beyoncé for her fourth studio album, "4" (2011).
 It features guest vocals from American rapper André 3000 and uncredited vocals from Kanye West, and was released by Columbia Records as the fourth single from "4" on August 30, 2011.
 The song was written by Kanye West, Jeff Bhasker and Beyoncé, with the production being handled by Beyoncé and West and was co-produced by Bhasker.
 A midtempo R&B song, "Party" exhibits elements of the 1980s funk and soul music, and samples the 1985 song "La Di Da Di", written by Dexter Mills, Douglas Davis and Ricky Walters.
 It recalls the work of New Edition and Prince, among others.
 Built on a 808-retro beat, multi-tracked harmonies, and a smooth groove, the song's instrumentation includes slow-bouncing synthesizers, keyboard tones, and drums. Lyrically, "Party" is about being "in the mood for some loving."
 In his rap verses, André 3000 references milk and gets philosophical about his own career.
 "Party" was nominated for Best Rap/Sung Collaboration at the 54th Grammy Awards.

 Nominations were announced on November 30, 2011 on prime-time television as part of "The GRAMMY Nominations Concert Live!

 Kanye West received the most nominations with seven.
 Adele, Foo Fighters, and Bruno Mars each received six nominations.
 Lil Wayne, Skrillex, and Radiohead all earned five nominations.
 The nominations were criticised by many music journalists as Kanye West's "My Beautiful Dark Twisted Fantasy" missed out on a nomination for Album of the Year despite being highly critically acclaimed and topping many end of year charts.
 West's album went on to win Best Rap Album.
"Lift Off" is a song by Jay-Z and Kanye West featuring American recording artist Beyoncé.
 It was written by Kanye West, Jay-Z, Jeff Bhasker, Mike Dean, Bruno Mars and Seal, while production was handled by West, Bhasker, Mike Dean, Pharrell, Q-Tip, and Don Jazzy for Jay-Z' s and West' s collaboration album, "Watch the Throne" (2011).

 However, Mars never appeared on the song and it was sent to urban contemporary radio on August 23, 2011.
The ARIA Albums Chart ranks the best-performing albums and extended plays in Australia.
 Its data, published by the Australian Recording Industry Association, is based collectively on each album and EP's weekly physical and digital sales.
 In 2013, thirty-six albums claimed the top spot, including Michael Bublé's "Christmas" and Pink's "The Truth About Love", both of which started their peak positions in 2011 and 2012, respectively.
 Sixteen acts achieved their first number-one album in Australia: Bruno Mars, Flume, Of Monsters and Men, Foals, Nick Cave and the Bad Seeds, Birds of Tokyo, Daft Punk, Queens of the Stone Age, Kanye West, Harrison Craig, Karnivool, RÜFÜS, Boy & Bear, Lorde, Dami Im and Taylor Henderson.
American singer-songwriter Bruno Mars has written and recorded songs for his studio albums, "Doo-Wops & Hooligans" (2010) and "Unorthodox Jukebox" (2012), and has written songs for other singers.
 The Smeezingtons (Bruno Mars, Philip Lawrence, Ari Levine) worked in the majority of the songs in Mars' debut studio album, including writing "Count on Me" and "Marry You" together.
 The team collaborated with Khari Cain and Khalil Walton on the album's lead single "Just the Way You Are", peaking at number one on the "Billboard" Hot 100.
 Mars explained "I wasn't thinking of anything deep or poetic.
 I was telling a story."
 Mars co-wrote and co-produced the song "Talking to the Moon" with Grammy Award winning producer Jeff Bhasker.
 The single "Grenade", was conceptualised after Mars heard an unreleased track with similar lyrical themes.
 Mars' follow-up album, in addition to reunite collaborators from his previous album, such as The Smeezingtons and Jeff Bhasker, included new composers, such as Mark Ronson and Emile Haynie.
 All of these producers worked on the lead single "Locked Out of Heaven".
 The song concerns a relationship infused with positive emotion and good sex.
 The idea behind the second single, "When I Was Your Man", is the regret of letting a girl get away.
 Several of the songs were written solely by his production team, including the lead single, "If I Knew" and the single "Gorilla"
