Marvin Gaye's family is responding in a major way to Robin Thicke's lawsuit claiming that "Blurred Lines" wasn't stolen from Gaye's "Got to Give It Up."

On Wednesday, the family went nuclear with counterclaims that allege that Thicke stole the summer mega-hit and also committed copyright infringement on Gaye's "After the Dance" to create his song "Love After War." What's more, the new legal papers obtained by The Hollywood Reporter suggest that Thicke's "Marvin Gaye fixation" extends to additional songs in the Thicke repertoire.

Perhaps even more consequential, Gaye's family also has set its sights on EMI April, the song publisher now owned by Sony/ATV that has business relationships with both sides. According to the counterclaims, EMI has breached a contract and its fiduciary duty by failing to protect Gaye's songs, attempting to intimidate the family against filing any legal action, failing to remain neutral when faced with a conflict of interest and attempting to turn public opinion against the family
