So the main argument here is to say "If this song wasn't a sucess the family would have not cared" but forgetting that the reason of this song being a sucess is that it samples an already established sucessful song that is Got to give it up by Marvin Gaye. There's absolutely no credit to give to Thicke or Williams on this one sorry not even the lyrics lol. So pay the family and admit you sample nothing wrong with that just give credit to Marvin please.
