context_page_description: Hot R&B/Hip-Hop Songs is a chart published by Billboard that ranks the top-performing songs in the United States in African-American-oriented musical genres; the chart has undergone various name changes since its launch in 1942 to reflect the evolution of such genres. In 1978, it was published under the title Hot Soul Singles. During that year, 22 different singles topped the chart, based on playlists submitted by radio stations and surveys of retail sales outlets.
  Three acts which formed part of George Clinton's Parliament-Funkadelic collective, known for its eclectic mix of funk and psychedelic rock and its use of science fiction imagery, topped the chart in 1978. In the issue of Billboard dated March 4, Parliament reached number one for the first time with "Flash Light". After three weeks in the top spot the single was displaced by "Bootzilla" by Bootsy's Rubber Band, led by bass guitarist Bootsy Collins, one of the collective's principal members. Finally, in September, Funkadelic gained its first chart-topper with "One Nation Under a Groove". Both Parliament and Funkadelic featured largely the same musicians, with the different names reflecting differing styles of music.
