Other pop songs based on "Space Invaders" soon followed, including "Disco Space Invaders" (1979) by Funny Stuff, "Space Invaders" (1980) by Playback, and the hit songs "Space Invader" (1980) by The Pretenders and "Space Invaders" (1980) by Uncle Vic. Buckner & Garcia produced a successful album dedicated to video game music in 1982, "Pac-Man Fever". Former YMO member Haruomi Hosono also released a 1984 album produced entirely from Namco arcade game samples entitled "Video Game Music", an early example of a chiptune record and the first video game music album. Warp's record "Testone" (1990) by Sweet Exorcist sampled video game sounds from YMO's "Computer Game" and defined Sheffield's bleep techno scene in the early 1990s.
