Disclosure dropped Settle, one of the best records of 2013, which spawned smashes like “Latch” with Sam Smith and “White Noise” with AlunaGeorge, among other gems — including “F For You.” The infectiously catchy throbber is more than enough of a groove to inspire some serious foolery on the dance floor as it stands, but the brother act decided to enlist a new voice — none other than the “No More Drama” titan Mary J. Blige herself — to give the track a soulful blast of energy. On Sunday, the songstress surprised the crowd at Terminal 5 with a surprise appearance during Disclosure’s set. And just like that, the studio version is already upon us.
