Take On Me is a 1985 synth-pop hit by Norwegian band a-ha, built around a catchy keyboard riff and Morten Harket's wide-ranging vocal. Its music video, which blends live action with pencil-sketch animation, became one of the most famous videos of the MTV era and helped the song reach number one in the United States. Decades later the chorus still circulates in memes, covers and retro playlists, because the melody is instantly recognisable even in a clip lasting only a few seconds.
