Sweet 19 Blues (song)

"Sweet 19 Blues" (stylized in all caps SWEET 19 BLUES) is the seventh single by Japanese recording artist Namie Amuro. It was composed, written and arranged by Tetsuya Komuro for her debut album of the same name. The single was released on August 21, 1996, by Avex Trax, following the album's success. The song's subject and the album in general was about the melancholic passing of another sweet year of youth, a particularly Japanese obsession.

Although it did not achieve the success of Amuro's previous singles, it still managed to debut at No. 2 on the Oricon Singles Chart with over 100,000 copies sold in its first week and eventually sold about half a million units overall. The single was certified platinum by the RIAJ for 400,000 copies shipped to stores.

The song was used as the ending theme song for the 1996 comedy film That's Cunning! Shijō Saidai no Sakusen?, in which Amuro also starred. Twelve years later, Miliyah Kato's 2008 hit song "19 Memories" sampled the song. In 2014, eighteen years after its release, a re-recorded version of "Sweet 19 Blues" was made for Amuro's compilation album Ballada. A rearranged version with new vocals was also included on Amuro's 2017 compilation album Finally.
