The Smeezingtons wrote most of the songs on Mars's debut studio album, including the lead single, "Just the Way You Are", along with Khari Cain and Khalil Walton. The singer conceptualized the song, "there's no mind-boggling lyrics or twists in the story – they just come directly from the heart".[3] On his second studio album, the Smeezingtons partnered with producer Jeff Bhasker, who also had a minor role in his debut record, as well as Mark Ronson, Emile Haynie and several other collaborators. Mars described making this album as "having the freedom and luxury of walking into the studio" and create "a hip-hop, R&B, soul or rock" song.[4] Shampoo Press & Curl, a trio formed by Mars, Lawrence and Christopher Brody Brown, co-wrote all the tracks on his third studio album with other composers.[5] Mars has said that the album was inspired by a non-existent movie that he visualized and the first single, "24K Magic", was its opening.[6] Mars co-wrote with Anderson .Paak, as Silk Sonic, their first collaborative album titled An Evening with Silk Sonic. They enlisted record producer and songwriter D'Mile to help Mars produce the album.[7][8] The duo felt "a competitive" and a friendly spirit emerged as they improved the songs written.[7]
Mars is also credited as a writer by the ASCAP as Peter Gene Hernandez.[1]
Bruno Mars was not credited as a featured artist on the first release of "6AM".[12] In 2012, he was credited on Bueno's mixtape Maloof Money, Vol. 3 (Executive Decisions).[13]
