A-ha's 'Take On Me' is famous for its revolutionary music video, but the song itself was a 'one-hit wonder' that almost wasn't. The track was released in two different versions before becoming a hit. The final, chart-topping version featured the now-iconic keyboard riff played on a Roland Juno-60. The music video used a technique called rotoscoping, where artists hand-drew 3,000 frames over live-action footage. This process took 16 weeks to complete. The video, which tells a story of a woman entering a comic book world, won six awards at the 1986 MTV Video Music Awards. The song's singer, Morten Harket, is known for his incredible vocal range, specifically the two-and-a-half octave leap to a high E note in the final chorus. It remains the most successful song ever by a Norwegian artist and has over 1.7 billion views on YouTube.
