There’s a certain progression to my opinions on Sigala tracks. Initially, I hate everything about them then return to my curmudgeonly ways. Soon after, I begin to see something in them, or at least am convinced to do so by a brain perhaps suffering from overexposure to them. Finally, the sun comes out and something clicks and I’m spinning around preaching whatever gospel Bruce Fielder of Norfolk is serving up. ‘Say You Do,’ interpolating Mariah Carey and featuring Imani and a firmly back-on-some-kind-of-form DJ Fresh, has reached stage 3 at record pace.
