Blinding Lights by The Weeknd opens with one of the most instantly recognisable progressions in recent pop memory: Am, F, C, G, cycling with a relentless, neon-lit momentum that feels both nostalgic and urgent. The minor start on Am gives the passage a cool, slightly melancholic weight, before F opens it outward and C resolves with reassuring warmth. The final move to G creates just enough forward tension to send the progression looping back, giving it that satisfying, perpetual-motion quality that makes it as rewarding to play as it is to hear. A flagship moment of the synth-pop revival of the late 2010s, the song wraps this classical harmonic logic in pulsing, retro-flavoured production that defined a particular mood of its era.
