I don't know why someone wouldn't pick Pharrell as their coach. If they win or even have a strong showing, they have one of the best music producers in the world in their corner.
I was telling my wife that last night. It's a no brainer.
Of course, I've been a huge Pharrell fan since his Neptunes days, so I'm obviously biased. My wife was still all #TeamAdam because, well, she's a she, and she likes Adam Levine.
