Sweet Dreams began as a 1983 hit by Eurythmics, built around one of the most recognisable synth riffs in pop music. Decades later, the melody has been endlessly remixed, sampled and reworked for dancefloors and social media, with funk-flavoured versions giving the riff a warmer, groove-led feel. On soundboards and short-form video, this style of remix is shared as a meme sound because listeners know it instantly, even without the original vocals. That instant recognition keeps it useful for edits, jokes and transitions long after the original chart run.
