Beastie Boys in fight with US toy company over viral video

But who's right? The girls-can-be-engineers toy startup or the no-music-in-ads hip-hoppers? It may be down to a judge to decide.

A legal row has broken out between hip-hop legends The Beastie Boys and an upstart US toy company with the viral video of the moment.

So who to back in this one - the avidly anti-commercial B-Boys or the perky little company with a message that girls can be engineers too?
