April: On 4/20, during an interview at Fenway Park, Dre, and Interscope founder (and Beats co-founder) Jimmy Iovine, announced that the lead single off Detox would be "Under Pressure", a collaboration with Jay Z.
A rip of "Under Pressure" leaked and received underwhelming reception among fans. Later in the year, Dre said "Under Pressure" wouldn't appear on the final album. Five years later, what do you think of the once potential single?
June: After producing 19 of 20 tracks on Eminem's double platinum Relapse (2009), Dre produced only two songs on Recovery--"So Bad" and "Ridaz", a bonus track.
Later that summer, Dre also announced an all-instrumental record, a full album of Beats By Dre. The project, he said, will be called The Planets, with one track to represent each planet in our Solar System.
November: A version of a song titled "Kush", featuring Akon and Snoop Dogg, leaked, and soon after, Dre put out the mastered version, confirming it would be Detox's (new) lead single. The single was produced by DJ Khalil, mixed by Dre, and, supposedly, the only marijuana-themed song on the album.
Dre soon put out a video, in which he starts and stops parties with the flick of a Zippo lighter.
