Pharrell Williams' 'Happy' may be another rip-off of Marvin Gaye song

Just a day after a judge awarded $7.3 million in the Blurred Lines case, Marvin Gaye's family claim they notice the similarities between Pharrell Williams' hit Happy and the late singer's Ain't That Peculiar.

The similarities between the two songs have been pointed out by some fans, including one who even made a mash-up for comparison purposes, reported CBS News.

Asked about their opinion, Gaye's daughter Nona Gaye said, "I'm not going to lie. I do think they sound alike."

"I heard the mash-ups - but I didn't really need to hear them," Gaye's ex-wife Janis added. "I know Ain't That Peculiar and I've heard Happy."

However, the family said that they had no plan to take legal action against singer Pharrell Williams. "We're not in that space," Janis said. "We're just in the moment today and we're satisfied."

In the meantime, Pharrell and Robin Thicke are planning to appeal against the verdict in the Blurred Lines case. Their lawyer Howard E King said earlier this week, "We are going to exercise every post trial remedy we have to make sure this verdict does not stand. We look at it as being in the seventh inning of a game that could go into extra innings."
