1 of 1

1 of 1 is the fifth Korean studio album and the ninth overall by South Korean boy band Shinee. It was released digitally and physically on October 5, 2016, under SM Entertainment and distributed by KT Music. The album contains nine songs, including the title track of the same name, "1 of 1". Musically, the album is a modernized twist on the retro genre, and stretches back to the 1980–1990 period. Additionally, based on their '90s theme, the group released a limited edition of cassette tapes alongside the CD version. In order to promote the album, Shinee appeared on several South Korean music programs, such as Music Bank, Show! Music Core, and Inkigayo, where they performed material from the album. On November 15, 2016, Shinee released a repackaged version of their fifth studio album titled 1 and 1 with five new songs, including the title track, "Tell Me What to Do". The album is also Shinee's last Korean album to feature Jonghyun prior to his death the following year. The album received favorable reviews from music critics, who praised Shinee's successful attempt at the retro style, bringing back the classic, old-school boy band sound, while maintaining the dreamy-like sound of their last album, Odd. It was commercially successful in South Korea and peaked atop the Gaon Album Chart, selling over 170,000 album copies in one month. The album also charted at number two on the Billboard World Albums chart. Its title track, "1 of 1", peaked at number four on the Gaon Digital Chart and number three on the Billboard World Digital Song Sales chart. The accompanying music video for "1 of 1" also received positive reviews. Stephanie Choi of Hello Asia and Gina Mei of Cosmopolitan praised the nostalgic feel of the video, as several aspects — the costumes, the simple, white backdrop, and old film transition techniques — reflect the retro style of the late 1980s and 1990s. Jeff Benjamin of Fuse praised the atypical portrayals of beauty, as the video includes many different looking female models. Background and release
