Released in 2005, The Black Eyed Peas' "Monkey Business" album contains 16 songs, including the chart-toppers "Don't Phunk with My Heart," "My Humps" and "Pump It." Several tracks also feature collaborations with other artists, such as Justin Timberlake and Timbaland's "My Style" and "Union" with Sting.
"Monkey Business" is the fourth studio album released by the hip-hop fusion group, a co-production with will.i.am Music Group and A&M Records. Despite mixed reviews, it sold over 10 million copies worldwide and was certified platinum three times in the United States and six times in both Canada and Australia.
In 2006, "Don't Phunk with My Heart" won the group a Grammy in the "Best Rap Performance by a Duo or Group" category, and other tracks scored them four nominations during that same award cycle. Many of the album's tracks sample other artists, including the Grammy-winning "Don't Phunk with My Heart," which samples Lisa Lisa & Cult Jam, and the controversial "My Humps," which pulls from Tone Loc's "Wild Thing" and Freestyle's "It's Automatic."
"Monkey Business," mostly recorded while on tour in 2004, is the group's second album as a quartet, with considerably more space given to its recently joined female vocalist Fergie, and much of the production work handled by singer-songwriter William Adams, otherwise known as will.i.am.
