"Genie" () is a song recorded by South Korean girl group Girls' Generation for their second extended play (EP) of the same name (2009), released on June 22, 2009. Written by Yoo Young-jin, and composed by Dsign Music, Fridolin Nordso and Yoo Young-jin, the song is the group's first collaboration with Western composers and producers.

Musically, "Genie" carried on the group's phase of bubblegum pop music from their debut. Lyrically, the song discusses the elements of love and relationships, alongside granting the wishes of their partner. It received generally positive reviews from music critics, many of whom highlighted the track as one of the highlights on the EP. The single was well received domestically, achieving the top spots on music programs Inkigayo and Music Bank.

Background and composition

"Genie" was composed by Norwegian production team Dsign Music members Anne Judith Wik, Robin Jenssen, Ronny Svendsen, and Nermin Harambašić, alongside Fridolin Nordsø and Yoo Young-jin. The Korean version was written by Yoo Young-jin, while the Japanese version was written by Kanata Nakamura. Yoo had originally composed a demo melody for an undisclosed artist outside of the group's label SM Entertainment. However, SM purchased the rights for the song and recommend it to Girls' Generation; as a result, Yoo re-composed the demo while Korean composer Yoo Han-jin re-arranged it.

The song was originally composed in English as "I Just Wanna Dance", but Yoo decided to scrap the idea after both sets of lyrics were written. Both versions were the groups' first singles to be composed and produced by Western producers, and had continued with future musical releases. Musically, both versions carried on the groups phase of bubblegum pop music since their debut in 2007.

According to Chucky Eddy from Spin, he found that the composition was inspired by "super-light-footed Italo disco..." A staff reviewer from CD Journal noticed musical elements of electropop and said the lyrics incorporates metaphorical uses of a lamp, genie, and Aladdin as themes of love and lust. Critic Lee Mun-won says that the song employs inspirations from trance and writes that the song itself is "more sophisticated than authentic europop."

Release

"Genie" was released digitally on June 22, 2009, in South Korea. In Japan, the song was released on September 8, 2010, as the group's debut Japanese single. The Japanese Maxi CD and DVD format of the single contains the Japanese version, the Korean version, and the karaoke version of the former. A limited edition CD and DVD format was released in both Japan and Taiwan; it featured a 14-paged booklet of photos, lyrics, and credits to the single, the original Japanese Maxi CD and DVD tracks, all housed in a digipak. The cover sleeve for both formats features Girls' Generation in different black and gold dresses, all standing in front of a white backdrop.
