GoldieBlox is being sued for the use of the Beastie Boys song in this clip. Turns out in his will Adam Yauch specifically asked that their works not be used for commercial purposes and the band('s lawyers) are honoring that request. Goldieblox will probably try to argue Fair Use but I think they're likely f'd because the primary purpose of this video is to advertise their products (the social commentary is incidental), which violates one of the factors of analysis the courts use in determining infringement.

Fair Use Wikipedia Entry: http://en.wikipedia.org/wiki/Fair_use

"No one really knows what I'm talking about
Yeah that's right my name's Yauch
Ponce De Leon constantly on
The fountain of youth not Robotron
Peace is a word I've heard before
So move and move and move upon the dance floor
I'm gonna die gonna die gonna die one day
Cause I'm goin and goin and goin this way
Not like a roach or a piece of toast
I'm going out first class not going out coach"

RIP Adam Yauch *promote

Nathaniel Hornblower is MCA (Adam Yauch) from the Beastie Boys, whose video for Sabotage was directed by Spike Jonze lost out to the turgid Everybody Hurts.

He quite rightly felt he needed to take a stand against this injustice.
