Most of the Pet Shop Boys' albums are well-crafted and thoroughly intriguing in their own right, but dance-pop is a medium that is driven by hit singles. Discography collects all the duo's numerous hit singles, including a handful of non-album tracks, in their original 7" single mix, which occasionally varies from the album version, particularly in the case of the Introspective material. Presented chronologically, the singles not only demonstrate the band's increasing musical sophistication, they illustrate what fine songwriters Tennant and Lowe are. These 18 songs form one of the most consistent and innovative bodies of work of its era. Some of the production techniques have dated slightly, but the music has remained impressive. ~ Stephen Thomas Erlewine, All Music Guide
