The late Adam Yauch has banned the use of Beastie Boys songs from being used in advertising, following his death.
The singer, who lost his battle with cancer earlier this year, made sure his will protected him and his work after his passing.
It read: "Notwithstanding anything to the contrary, in no event may my image or name or any music or any artistic property created by me be used for advertising purposes."
The will, which was filed in Manhattan on Tuesday, also specifies that his $6.4m fortune should be placed in trust for his wife, and their 13-year-old daughter.
Yauch founded the Beastie Boys with rappers Ad-Rock and Mike D in the 1980s and went on to have huge success with the likes of Fight for Your Right (to Party) and Sabotage.
Tributes have flooded in to Yauch since his death, with the band returning to the US Top 20 and the New York State Senate even honouring the late rapper.
