"Can't Sleep, Can't Eat, I'm Sick / Ningyo" is a song by Japanese singer Namie Amuro from her eighth studio album Play (2007). It was released as a single on May 17, 2006, by Avex Trax, as the album's second single. Although she has had Japanese song titles prior to signing with Avex Trax, "Ningyo" or "人魚" which means mermaid, is her first with the label. "Can't Sleep, Can't Eat, I'm Sick" is featured on the album Play, although the latter A-side, "Ningyo" or "人魚", was excluded. Background In 1994 Amuro appeared in the drama "Toki wo Kakeru Shoujo" which used the original "Ningyo" as its ending theme song. During the release of Queen of Hip-Pop (2005) to "White Light / Violet Sauce" (2005), Namie predominantly worked with producer/songwriter, Nao'ymt. This single reunites her with producers T.Kura and Michico who crafted many of her early R&B hits in 2003. "Can't Sleep, Can't Eat, I'm Sick," produced by the pair has been described as a funky summer dance tune. The other a-side, "Ningyo," is a cover of Japanese artist, Nokko, who made the song a massive hit in 1994, and is a theme song of TV drama "Toki o Kakeru Shojo" in which Amuro played a younger sister of Yuki Uchida who is a leading actor. For the production of the music video for "Can't Sleep, Can't Eat, I'm Sick", Namie teamed up with American choreographer Shawnette Heard. Shawnette Heard has danced and choreographed routines for many of the world's biggest musical artists including Christina Aguilera, Janet Jackson, Michael Jackson, Madonna, Ricky Martin, Mýa, and many more. On May 17, 2006, along with the release of the single her complete solo catalog was released to iTunes Japan. Immediately afterwards, "Can't Sleep, Can't Eat, I'm Sick" and "Ningyo" ranked #4 and #6 respectively. Commercial endorsements "Can't Sleep, Can't Eat, I'm Sick" was used in commercials for ringtone service sites, Mu-Mo and Iromelo Mix DX. "Ningyo" was also used in commercials for Mu-Mo. Music video The promotional video for "Can't Sleep, Can't Eat, I'm Sick" debuted on music channel, VMC on May 1, 2006. Directed by longtime collaborator, Masashi Muto, the video focuses entirely on a dance routine choreographed by Shawnette Heard. It is also reminiscent of Kylie Minogue's "Can't Get You Out of My Head" (2001) as a majority of it is filmed in a dark room entirely adorned in lights. It
