Background and content
In January 2007, Hamasaki announced on her website that she planned to release two greatest hits albums, titled A Best 2 (individually referenced as Black and White). Both Black and White are direct follow-ups to Hamasaki's compilation album A Best, which debuted in March 2001 to immense commercial success. It is also Hamasaki's third and fourth compilation album, released four years after her ballad-inspired collection A Ballads (2003). On 17 January, Hamasaki published additional information about both albums, including the album's content, formats, and promotional activities.

A Best 2 are concept albums, with Black focusing on darker and more serious tones and White on lighter and more upbeat themes. Black and White features 31 songs from Hamasaki's single releases between her albums I Am... (2002) and (Miss)understood (2005). They both include tracks that were not released as singles; Black includes "Walking Proud," "About You," and a new recording called "Part of Me," while White features "Humming 7/4" and "My Name's Woman." Additionally, the song "Memorial Address" was added as a hidden track to Black.

Reception
A Best 2 received positive feedback from the Japanese music publication CDJournal, which reviewed each album individually. The review praised Black for featuring "dramatic" ballads in the first half and primarily rock music in the second half. The publication also highlighted "Heaven" and "Part of Me" for concluding the album with "expressive" vocals from Hamasaki. The second review for White praised songs like "Evolution" and "Grateful Days" for being a "positive" aspect to the record, as well as how well the album complement Black.
