"Butterfly" is the third single from the South Korean singer G-Dragon's first album Heartbreaker. It was released about a month after the release of his song "Breathe".
Although the end of his "Breathe" music video included a teaser for his song "A Boy", the song "Butterfly" was released first. In contrast to his previous singles (which were more upbeat, "Butterfly" has a slower tempo. G-Dragon himself describes the song as "calming" while the critic for the Newsen described it as "romantic", stating that the song has an "exotic romantic rap lyrics [...and] sweet harmony vocals that appeal particularly to couples in love." The song went to the top of various charts upon its release.
While his two singles showcased G-Dragon dancing with a white backdrop, "Butterfly"'s music video heavily concentrated on computerized graphics. The singer himself was computerized for several moments throughout the music video. The girl in the video, however, was completely computerized. YG Entertainment has described the video as a "specially crafted music video [...] scheduled to coincide with the publicity." The music video has drawn more than 4,000,000 views on YouTube.
G-Dragon was again accused of plagiarism with "Butterfly" when Sony Music stated that the song was similar to Oasis's "She's Electric". All charges have since been lifted against G-Dragon.
