"Pieces of a Dream" is the first single from the Japanese R&B (J-urban) band Chemistry.

Since the band won a contest similar to the American Idol show, the single was expected to be a success.

Although the single debuted at #2 on the Oricon charts, it finally reached #1 after 6 weeks.

"Pieces of a Dream" was the third-highest ranking single of 2001, selling over one million copies.

In 2016, the song was featured in the Anime, ReLIFE for episode 11 ending theme.
