Flicker is a track by American electronic producer Porter Robinson, released on his debut album Worlds in 2014. The album marked a shift toward bright, melodic, anime-inspired electronic music, and Flicker became one of its most recognisable cuts among fans of the genre. Short excerpts have since circulated online in edits, montages and fan videos, where the track's uplifting sound suits colourful visuals and celebratory moments. Its lasting appeal comes from that instantly recognisable melody and the nostalgia many listeners attach to the Worlds era.
