The To-Y anime is best known for its excellent music, with pop and rock songs permeating the action, not merely background music (BGM), but part of the story. The images complement the music just as the music complements the images. In that sense, To-Y functions much like a narrative music video.
If the music in To-Y seems appropriate to match the story and its imagery, perhaps it is because Atsushi Kamijo, while he was researching the underground club scene for To-Y, hung out with the various artists who perform on the soundtrack. Also, much credit must be given to Masaya Matsuura, who was selected to be the anime's music director.
The music director of To-Y was Masaya Matsuura, of Psy-s, a Japanese pop band. Psy-s was most popular in the eighties, is known for its consistency, and has a loyal fan-following. The anime uses several Psy-s songs, and Matsuura also arranged many of the non-Psy-s songs on the soundtrack. Matsuura's recent claim to fame was his role as the music director of Parappa the Rapper, the smash-hit Playstation game.
Most of the songs listed below can be found on the To-Y Original Image Album, which is inaccurately named as it is essentially the anime's soundtrack. Unfortunately, four very excellent songs, Bruce, Teenage, Silent Song, and the Uptown Traffic/Lemon no Yuuki: Special Remix Edit Version, are not on this album. Silent Song can be found on the Psy-s Collection album. Bruce can be found on Hajime Mizoguchi's Oasis-behind the clear water album. The original mix of Teenage can be found on the Psy-s Different View album, but the mix of Teenage used in To-Y has not been released on CD as far as I know, nor has the Uptown Traffic/Lemon no Yuuki remix.
The catalog number for the To-Y Original Image Album is CBS/SONY #32DH 775. More information on this CD can be found at Jerry Hsu's YAACC (Yet another Anime CD Cyclopedia). For fans in Taiwan, or those who like Taiwanese anime products, the To-Y Original Image Album is listed as SM-054, reference number 32DH 775.
