We've been paying close attention to London-based Rationale for a few years now — thanks in no small part to disarmingly likeable drops "Fast Lane", "Re.up." and "Prodigal Son". Now he's back with brand new single "Say What's On Your Mind", a gloriously smooth piece of funk-drenched R&B with thick, juicy bass lines and seductive falsetto vocals. I got 21 questions and I hope you have patience for me, he croons sweetly in a way that will have you utterly enraptured. There are whispers that a new project is coming our way, although details remain scarce right now. Regardless, it's a step away from the big, catchy hooks he made his name on, but if this is anything to go by, whatever this project looks like, it'll be one to remember.
