When Paris-based branding agency Agenda monitored brand mentions in the Billboard Hot 100 from 2003 to 2005, the company found brands and products were most frequently name-checked in hip-hop.

That's hardly a surprise to anyone who possses a passing familiarity with contemporary pop music. And an examination of Billboard's list of the top Hot 100 songs of all time shows that hip-hop acts alone account for six of the 10 songs that mention brands.

While other genres tend to deal with more abstract concepts, hip-hop is often direct and visceral, says Agenda founder and president Lucian James. "In other styles of music, it's more general themes--love, happiness and missing people, which doesn't really lend itself to brands,'' he says.

"The thing you notice [about] a lot of the main players that always get mentioned--Hennessy, Mercedes-Benz, Cadillac--is these brands always crop up because they are the best shorthand for success and material wealth," James says. "It's a poetic way to use language. When you say 'Benz' you're not just mentioning a product, you're connecting to a whole set of values and how you see yourself in just four letters."

Agenda stopped monitoring brand mentions in 2005 because its agenda, as it were, had been fulfilled. "It was a time when Jay-Z and Kanye West were seeming to understand what luxury brands were,'' James says. "They were wearing them and talking about them. It was the first wave of that and now it's kind of matured. Now it's a lot more structured. Luxury brands have learned more about themselves from their relationship with hip-hop in the past four to five years than in the past 10."

What follows is a listing of the songs in the Billboard's all-time Hot 100 that mention brands.
