Pharrell's a great producer, not to mention a singer aswell. I've never heard someone with a voice like him. I believe he's almost just as creative as Frank Ocean. Not to be a dickrider or anything, I personally just enjoy their music very much.
I'm currently reading Pharrell's book and it's fucking spiffy. I recommend it to any fans of his or just wanting to know how he all started out and what he did during his prime.
