In 2007, Dr. Dre's third studio album, formerly known as "Detox", was slated to be his final studio album. Work for the upcoming album dates back to 2001, where its first version was called "the most advanced rap album ever", by producer Scott Storch. Later that same year, he decided to stop working on the album to focus on producing for other artists, but then changed his mind; the album had initially been set for a fall 2005 release. Producers confirmed to work on the album include DJ Khalil, Nottz, Bernard "Focus" Edwards Jr., Hi-Tek, J.R. Rotem, RZA, Jay-Z, Warren G, and Boi-1da. Snoop Dogg claimed that "Detox" was finished, according to a June 2008 report by "Rolling Stone" magazine. After another delay based on producing other artists' work, "Detox" was then scheduled for a 2010 release, coming after 50 Cent's "Before I Self Destruct" and Eminem's "Relapse", an album for which Dr. Dre handled the bulk of production duties. In a Dr Pepper commercial that debuted on May 28, 2009, he premiered the first official snippet of "Detox". 50 Cent and Eminem asserted in an interview on BET's "106 & Park" that Dr. Dre had around a dozen songs finished for "Detox".
