The instrumental on here actually sounds like something we'd here Floetry on whilst Poet22's vocals exudes an aura reminiscent of Summer Walker.
I love the fact that "crazy 4 u" has a 2000's R&B feel emblazoned with a modern touch, and there is also something about her soulful performance which seamlessly pulls the listener in with it's romance imbued songwriting too. If you're looking for a track to set the mood right with that special person... Look no further than "crazy 4 u".
