The Beastie Boys' Adam Yauch rapped that he wouldn't "sell my songs for no TV ad."
His will shows he wanted to make sure that held true after his death.
The will was filed in a Manhattan court this week, three months after his death from cancer at age 47. It says his image, name, music "or any artistic property" he created can't be used for advertising.
His lawyer and the band's spokesman declined to comment Friday.
Also known as MCA, Yauch was a founding member of the Beastie Boys, who helped hip-hop gain mainstream attention in the 1980s. They've enjoyed four No. 1 albums and sold more than 40 million records.
Yauch's leaves his roughly $6 million estate to his widow and daughter.
