181920 (pronounced: “one-eight-one-nine-two-zero”) is the first greatest hits album by Japanese musician Namie Amuro, released under the Avex Trax label on January 28, 1998. The album commemorates Amuro’s marriage and pregnancy, and covers twelve singles which were released prior to her maternal hiatus in 1998, three of which had been originally released under her previous label, Toshiba-EMI. The title of the album derives from the fact that its material spans those three ages in which she recorded and performed these songs. Her 9th single, "Dreaming I was Dreaming" is exclusive to the album not appearing on any of her original studio recordings.
