The Hallelujah chorus comes from Handel's Messiah, first performed in Dublin in 1742, and has long been used to mark triumph and celebration. In recent online meme culture, producers have reworked familiar choruses with bitcrushing and other lo-fi effects, giving a grand sound a deliberately degraded, internet-era texture. That treatment turns a formal choral moment into something shareable and funny, which is why short, distorted versions keep appearing in edits, reaction videos and gaming clips.
