Lawyers for Pharrell and Robin Thicke were too clever by half and played this wrong from the beginning. The pre-emptive lawsuit pretty much established that the writers and producers were at least acknowledging similarities between Blurred Lines and Got to Give It Up, and since it was actually brought before a court, the Gaye estate had no reason not to counter-sue as they had to respond to the suit anyway. They were probably surprised when they ended up winning. The percussion on the songs is stylistically similar, but Blurred Lines didn't use an actual sample of Got to Give It Up. So, I think that when all is said and done -- and after all of the lawyers have gotten all of the royalties -- Pharrell, Thicke, and T.I. will prevail. If both parties were smart, they'd settle and at least salvage those coins before they evaporate in legal fees. The problem is, it's not in the interest of the lawyers to settle, b/c as long as this goes on, they get money.
