Ayumi Hamasaki's first album in 15 months since her mega-hit 3rd album! It contains all singles she released between December 2000 and September 2001, and previously unpublished (on CD format) songs that have been used in commercials, plus new stuff showcasing her creativity, of course! Since the hit of her single "M," she's been composing her own songs under the pseudonym CREA, and she's been doubling as her own stage producer on her own live concerts.
