PCD is the debut album by the American pop group The Pussycat Dolls, released in 2005. The record blends dance pop and R&B with bold, seductive production and grew the group out of their origins as a burlesque dance troupe. Hit singles such as "Don't Cha", "Buttons", "Stickwitu" and "Beep" defined the sound of the record. The songs alternate uptempo dance numbers with the occasional ballad. The album established the Pussycat Dolls as one of the best-known pop groups of the mid-2000s.
