More “Blurred Lines” controversy: As expected, Marvin Gaye’s family has formally filed a lawsuit for copyright infringement against Robin Thicke and Pharrell Williams over “Blurred Lines,” which they claim steals a major portion from Gaye’s 1977 song “Got to Give It Up,” Reuters reports.

After “Blurred Lines” debuted there were rumblings about the similarities, so Thicke and Pharrell filed a preemptive suit in August, claiming the summer smash did not infringe. In this counter-suit, the Gaye family also claims Thicke’s 2011 song “Love After War” lifts from Gaye’s 1976 “After the Dance.” They are asking for a portion of profits from both songs, in addition to up to $150,000 for each alleged infringement.
