Rather than imitate the original's glossy studio production, the arrangement rebuilds the song from voices alone, planting the famous melody in the Tenor 2 line and ringing barbershop-tinged harmonies around it. Vocal-percussion syllables and sustained pads stand in for the drum machine and synth bed, giving the chorus a buoyant, self-propelled groove.

Wright's chart strips the 2012 pop hit, written by Swift with Max Martin and Shellback, down to a nimble a cappella frame. Without a band to lean on, the ensemble itself becomes the rhythm section, snapping out the chugging eighth-note pulse with consonants and clipped vowel hits while the close harmonies stack into bright, slightly tart chords that mirror the song's eye-rolling defiance.
