Zynga has announced that they have signed a deal with Dr. Dre. The in-game music partnership will let players stream the video Kush, featuring Snoop Dogg and Akon, free within Mafia Wars and purchase the song via an iTunes link in the game.

“We’re always looking for innovative and interesting ways for fans to discover great music and with an artist of Dre’s cultural significance we really wanted something special that s never been done before,” said Jimmy Iovine, Chairman, Interscope Geffen A&M Records. “We felt it was a perfect fit for Dre to be the first musical experience for the millions of Mafia Wars players to enjoy while gaming.”

“Mafia Wars players will also be able to collect Dr. Dre inspired virtual goods such as headphones, a vintage car, and weapons. Players will also be able to watch a Dr. Dre video message and become eligible to win signed Dr. Dre headphones and a signed copy of the CD Detox when it becomes available next year.”

“Dre is a cultural icon that has inspired generations of music lovers,” said Mark Pincus, CEO and founder of Zynga. “We’re huge music fans at Zynga and we know the players within Mafia Wars will love the chance to discover incredible music content while playing with their friends.”
