Hard Candy 2.0, anyone?
To refresh your memory, Pharrell executive produced nearly every song off Madonna’s eleventh studio album, 2008’s Hard Candy. If he wasn’t behind a track, his industry buddy Justin Timberlake was, and it was one of her best records to date. Yeah, I said it.
This may not seem significant, but it's a window into the direction Madonna's Rebel Heart followup could go. Your move, Pharrell.
