In 1982, Kraftwerk began work on a follow-up album to its successful and influential "Computer World". This new album initially had the working title "Technicolor" but that name had to be abandoned because it was a trademark. The proposed new title was "Techno Pop". The initial track listing consisted of four tracks. The first track, "Techno Pop", would take up one side of the LP and was an original one-track mix of "Boing Boom Tschak", "Techno Pop" and "Musique Non-Stop", as they appeared on the final album. On the other side were the tracks "The Telephone Call", "Sex Object" and "Tour de France".
