Critics such as Businessweek's David Kiley argue that the discussion of many products within hip hop music and culture may actually be the result of undisclosed product placement deals. Such critics allege that shilling or product placement takes place in commercial rap music, and that lyrical references to products are actually paid endorsements. In 2005, a proposed plan by McDonalds, which would have paid rappers to advertise McDonalds food in their music, was leaked to the press. After Russell Simmons made a deal with Courvoisier to promote the brand among hip hop fans, Busta Rhymes recorded the song "Pass The Courvoisier". Simmons insists that no money changed hands in the deal.

The symbiotic relationship has also stretched to include car manufacturers, clothing designers and sneaker companies, and many other companies have used the hip-hop community to make their name or to give the credibility. One such beneficiary was Jacob the Jeweler, a diamond merchant from New York, Jacob Arabo's clientèle included Sean Combs, Lil Kim and Nas. He created jewelry pieces from precious metals that were heavily loaded with diamond and gemstones. As his name was mentioned in the song lyrics of his hip hop customers, his profile quickly rose. Arabo expanded his brand to include gem-encrusted watches that retail for hundreds of thousands of dollars, gaining so much attention that Cartier filed a trademark-infringement lawsuit against him for putting diamonds on the faces of their watches and reselling them without permission. Arabo's profile increased steadily until his June, 2006 arrest by the FBI on money laundering charges.
