Believer was released by Imagine Dragons in 2017 as a single from their album Evolve, and its pounding drum-led sound quickly made it a staple of trailers, sports broadcasts and motivational edits. As short-form video grew, creators began cutting the track down to its hardest-hitting second or two, turning that burst of energy into a reusable reaction for comebacks, reveals and hype moments. The clip survives because it is instantly recognisable even at this length, needing no lyrics or context to signal confidence and momentum.
