"Bye Now!" (stylised as BYE NOW!) is a song recorded by Japanese born-South Korean singer Iconiq, marketed as the lead single of her debut Studio album, Change Myself, released in March 2010.

It was widely played at radio stations during the album's release, peaking at #8 on the Billboard Japan Hot 100.^[1] The song was also included on her extended play Light Ahead in September 2010.

The song is a synthpop/R&B song, written by Michico, T. Kura, the writers of Iconiq's debut single "I'm Lovin' You." The lyrics of the song describe an everyday scene, in which the subject of the song is dissatisfied with her life. She "purposely spills her coffee everywhere" and thinks that "every single day is like a ceremony." She decides to work against this daily pressure, by saying goodbye to this "dangerous pressure" and "complex that everyone, even her boyfriend has" by being true to herself.^[2]

The song was used in commercials for Shiseido's Maquillage make-up range and starred Iconiq as the spokesperson, the third successive song of Iconiq's to have this, after "I'm Lovin' You" and "Change Myself."^[3] During album promotions, Iconiq promoted products from seven different companies simultaneously: All Nippon Airways, US fashion brand Kitson, Italian car manufacturer Maserati, Rhythm Zone, music download site Mu-Mo, Shiseido and Starbucks.^[4] Each commercial had two versions: one featuring "Bye Now!" as background music, along with versions using"Change Myself."^[5]

Iconiq performed this song as a per of her set at the 2010 A-Nation concerts.^[6]

The music video was directed by Hisashi Kikuchi.^[7] The video centres around scenes of Iconiq performing a dance routine with several similarly dressed backup dancers, in a distinctive red hat. Several scenes of this dance are shot in the dark, and lit with fluorescent lighting that comes from each dancers' clothing. Also interspersed between these scenes are shots of Iconiq in different outfits, as she sings the song to the camera.

The music video was aired heavily in early March on several music video channels, such as MTV Japan's Buzz Clip, MJTV's MJ Bound, Music On!'s Rookie and VMC's Video of the Week.^[8]
