Back in August, Robin Thicke and Pharrell filed a preemptive lawsuit against Marvin Gaye’s family, telling them to back off with copyright infringement claims. That did not work out. The family filed a counterclaim today that alleges Thicke copied both “Got to Give It Up” (for “Blurred Lines”) and “After the Dance” (for “Love After War”). The suit points to multiple interviews in which Thicke himself admits a debt to Gaye and singles out critics who made the comparison. The family is also suing EMI — which works with both parties — for “failing to protect Gaye’s songs” and for bullying them against legal action. In summary: This fight is really on.
