Yes, we've made that pun we just made in the headline a few times before, like how Robin Thicke blurred the lines of what being faithful in a marriage to Paula Patton meant, but this time there's just no way around it.
The singer whose 2013 hit "Blurred Lines" sparked controversy for many reasons (date rapey lyrics, sexist video, ripoff of a Marvin Gaye song) has added a new controversy to further sully the song's reputation. It turns out that he didn't even have a hand in writing it! In court deposition documents obtained by the Hollywood Reporter (for that aforementioned Marvin Gaye ripoff lawsuit: Gaye's family alleged — rather rightfully — that "Blurred Lines" sounded a heck of a lot like "Got to Give it Up") Thicke said, "I was high on vicodin and alcohol when I showed up at the studio. So my recollection is when we made the song, I thought I wanted — I — I wanted to be more involved than I actually was by the time, nine months later, it became a huge hit and I wanted credit. So I started kind of convincing myself that I was a little more part of it than I was. … But the reality is, is that Pharrell had the beat and he wrote almost every single part of the song."
So yeah, blurred lines of authorship due to blurred senses from booze and pills.
