Butterfly by SMiLE.dk

"Butterfly" is a song by Swedish bubblegum dance group Smile.dk from their 1998 album Smile. It was written and produced by Robert Uhlmann and Robin Rex. The song gained popularity outside of Sweden when it was included on the first version of Konami's music video game, Dance Dance Revolution and Dance Dance Revolution 3rdMix. In honor of its popularity, the song was remixed for the franchise's 2008 installment Dance Dance Revolution X, a mix primarily intended to celebrate the 10-year anniversary of the series. The song also became an internet meme in the 2010s after being included in made-in-China toy phones. In 2009, the song was re-recorded with Veronica and Malin doing the vocals. This version was released as a single on May 13, 2009 and was titled "Butterfly '09 (United Forces Airplay Edit)". South African band Die Antwoord sampled the song in their hit "Enter the Ninja" having heard it on Dance Dance Revolution X.
