In Adam Yauch's will, the now-gone rap icon prohibited the use of Beastie Boys songs in advertisements and the group's two remaining members, Ad-Rock and Mike D, are doing their best to uphold Yauch's wishes. Now that a toy company GoldieBlox has used their material in a video advertisement promoting its toys, the boys are not too happy and have taken action.

Just replacing the original lyrics on the Beastie Boys hit "Girls," with those that are empowering to little girls, it's apparent that there was indeed some miscommunication. As Ad-Rock and Mike D claim that they knew nothing about this, they are citing copyright infringement against the company, penning the letter below:

"Like many of the millions of people who have seen your toy commercial “GoldieBlox, Rube Goldberg & the Beastie Boys,” we were very impressed by the creativity and the message behind your ad. We strongly support empowering young girls, breaking down gender stereotypes and igniting a passion for technology and engineering.
As creative as it is, make no mistake, your video is an advertisement that is designed to sell a product, and long ago, we made a conscious decision not to permit our music and/or name to be used in product ads. When we tried to simply ask how and why our song “Girls” had been used in your ad without our permission, YOU sued US."
