Discipline was and remains garbage with about 5 redeemable songs. The only forward-thinking songs on it are Feedback and RWU. The article saying it's "the album she needed to release," lmao, as if there was some artistic impetus for it when it was clearly just thrown out there to fulfill obligations and attempt a weak chart return.
And RWU would never have been a pop hit because 1) it's 100% whispered, 2) it lacks a catchy hook, and 3) it has one verse repeated. It's a dance hit and that's that. Not every EDM song becomes a smash in Europe, for that you need a real chorus.
