 Kraftwerk's musical style and image can be heard and seen in 1980s synth-pop groups such as Gary Numan, Ultravox, John Foxx, Orchestral Manoeuvres in the Dark, The Human League, Depeche Mode, Visage, and Soft Cell.Kraftwerk influenced other forms of music such as hip hop, house, and drum and bass, and they are also regarded as pioneers of the electro genre.Most notably, "Trans Europe Express" and "Numbers" were interpolated into "Planet Rock" by Afrika Bambaataa & the Soul Sonic Force, one of the earliest hip-hop/electro hits.
