Sia released The Greatest in 2016 as an anthemic pop single, and its soaring chorus made it a natural fit for harder dance reworks. Frenchcore, a fast and distorted offshoot of hardcore techno, pushes that vocal into a much more aggressive context, pairing emotional melody with relentless kicks. Clips like this circulate on soundboards and in short edits because the contrast works instantly: listeners recognise the song, then feel the sudden jump in intensity that suits high-energy videos.
