Planet Rock: The Album is an old school hip hop album by Afrika Bambaataa & Soulsonic Force, released in 1986 as a collection of previous singles. The song "Planet Rock" was one of the earliest hits of the hip hop music genre and remains one of its pioneering recordings. The single's liner notes include members of Kraftwerk with the songwriting credits. In creating the track, portions of Kraftwerk's "Numbers" and "Trans-Europe Express" were interpolated (re-recorded in the studio, rather than through the use of a digital sampler), along with portions of songs by Captain Sky and Ennio Morricone.
