Not sure what the deal is with the Beastie Boys lately, but the iconic hip-hop group seems to be spending a lot more time suing for copyright infringement than rocking mics.

Today at the Thurgood Marshall Courthouse in Manhattan the Beastie Boy's lawsuit against Monster Energy drink went to trial. The Beasties are suing over the use of their songs in a promotional video posted to YouTube by Monster.

The video, which contained footage from a snowboarding event in Canada hosted by Monster, featured a "Beastie Boys Megamix" by Z-Trip that included samples of 'So What'cha Want', 'Sabotage', 'Looking Down the Barrel of a Gun,' and 'Make Some Noise'.

The video was posted shortly after the death of Beastie Boy Adam "MCA" Yauch, who succumbed to salivary gland cancer in May of 2012. In Yauch's last will he stated that his music could not be used for advertising purposes.

Monster has released a statement saying they believed that they had the rights to use the music. Monster attempted to put the blame on Z-Trip, but that argument was dismissed by a judge. Now a jury will decide fair compensation to the Beastie Boys for unlawful use of their tunes.

The prosecution seeks $1 million in damages for the song licenses and another $1 million for the "implied endorsement" of the Beastie Boys' association with the video. Monster finds this a bit excessive, claiming the incident was a mistake, and the video, which was only online for a brief period, only received about 14,000 views. Monster is arguing that damages should not exceed $125,000.

Billboard reports Ad-Rock has testified that the group does not license its music, as this is "a form of selling out." In rebuttal, Monster's attorneys showed the jury a photo of Mike D dressed as a sailor in a Nixon watch ad.

The Beastie Boys are no strangers to copyright laws. Last year the band was involved in a lawsuit with GoldieBlox toy company over the use of their song 'Girls' in an advertisement. That suit was settled out of court.

Prior to that, the Beastie Boys found themselves defendants in a copyright suit from Tuf America, who claimed the group committed copyright infringement by sampling other artists.
