Hikaru Utada

Hikaru Utada (宇多田 ヒカル Utada Hikaru), known by her stage name Utada (English pronunciation: /ˈuːtədə/) in America and Europe, and as Hikki (ヒッキー, Hikkī?), is a Japanese American singer and songwriter, arranger, and record producer.

Before her First Love album (1999), she sold several records with mediocre success. After First Love's release, which went on to become the best-selling album in Oricon's recent history, Utada has three of her Japanese studio albums in Top 10 best-selling albums ever in Japan (numbers 1, 4, and 8 ) and an overall six of her albums, two English-language and one compilation, charting within the 275 Best-Selling Japanese albums list.

Utada has had twelve number-one singles on the Oricon Singles chart, with two notable record achievements for a female solo or group artist: five million-sellers and four in the Top 100 All-Time Best-selling Singles. For her achievements, she was described by Time Magazine in 2001 as a "Diva On Campus," while attending Columbia University for a brief, career-break semester in 2001. In 2003, Utada was ranked #24 in the survey of Top 100 Japanese Pop Artists of All Time by HMV, and #10 in HMV's Top 30 Best Japanese Singers of All Time in 2006.

Additionally, Utada made two theme song contributions to Square Enix's Kingdom Hearts video game series: "Simple and Clean" and "Sanctuary". In 2007, her single "Flavor of Life" reached #2 in worldwide digital download yearly single chart with over 7.2 million downloads, and contributes to 12 million digital sales for her over the same year.

I couldn't find a good or existing music video for the last one except for a poor version of a live concert version.
