M by 浜崎あゆみ

"M" is a song written by Japanese singer Ayumi Hamasaki from her album I Am... (2002). The lead single from the album and Hamasaki's nineteenth overall, "M" marked Hamasaki's increased creative control over her music, as it was the first song she composed, under the pseudonym "CREA". The single is to date one of Hamasaki's most commercially successful; it peaked at the top spot on the Oricon weekly charts, selling over 500,000 units on its first week. Moreover, the single eventually sold over 1,000,000 copies over its seventeen-week run and became a RIAJ-certified million-seller; "M" also won the Japan Gold Disc Award for "Song of the Year".
