181920 (pronounced One Eight One Nine Two Zero) is Namie Amuro's first singles collection under the avex trax label. The album covers twelve singles which were released prior to her maternal hiatus in 1998. 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.
