Thunderstruck is a song by Australian rock band AC/DC, released in 1990 on the album The Razors Edge. Its opening guitar riff and explosive energy helped it become one of the band's most recognisable tracks. Online, short cuts of the song spread through sports edits, hype compilations and meme videos because the sound instantly signals adrenaline and anticipation. It remains popular years later because even a one-second snippet is enough for many listeners to recognise the track and expect something dramatic.
