Ever since “1+1,” which was first recorded and written by The-Dream—another artist who wears his purple heart on his sleeve—and Tricky Stewart, Beyoncé has sounded more and more like P. Check out “Blow”—produced by Pharrell and with risqué lyrics written by Justin Timberlake—from B’s self-titled fifth album, sounds like a Vanity 6 outtake. And then there was “Rocket”—another Timberlake composition, with a little help from Miguel—“So rock right up to/The side of my mountain/Climb until you reach my peak babe, my peak, the peak/And reach right into the bottom of my fountain…” You get the picture. Just for the record: all this happened long before Jay signed Prince to Tidal. But even her harsh vocal tone on the future funk of “Formation” sounds like some “Housequake” era Prince.
