Robin Thicke, Pharrell, and T.I. have preemptively sued the children of Marvin Gaye over a threatened lawsuit that "Blurred Lines" copies Gaye's 1977 hit "Got to Give It Up."

"Blurred Lines" if you don't know (because you have been living deep beneath the surface of the Earth and the mole people are "Get Lucky" partisans) is the song of the summer, simultaneously playing on every radio station at every moment in every part of the country.

Gaye's children, however, are less than pleased by a song they consider to be more than just an homage to their father. Pharrell and Thicke admitted that while writing the song, they were inspired by Gaye, although they did not copy him.

“Pharrell and I were in the studio and I told him that one of my favorite songs of all time was Marvin Gaye’s ‘Got to Give It Up,’ ” Thicke told with GQ. “We should make something like that, something with that groove."

The lawsuit, which is annotated over at Rapgenius, begins with the following statement:

The Plaintiffs, who have the utmost respect for and admiration of Marvin Gaye, Funkadelic and their musical legacies, reluctantly file this action in the face of multiple adverse claims from alleged successors in interest to those artists.

The lawsuit also seeks to protect the artists from a lawsuit by George Clinton, whose music publisher contends that the song also infringes on Clinton's song “Sexy Ways.” But George Clinton descended from the Mothership to tweet that he supports Thicke and Pharrell, and that there was no infringement.

I will not be linking out to "Blurred Lines" because you can probably hear it at this moment, being played by three cars in your proximity, and being hummed by anyone else in the room. You are probably singing it right now.
