This funk classic was a big hit for Funkadelic, and is today regarded as one of their signature songs, being a part of the Rock and Roll Hall of Fame's 500 Songs That Shaped Rock and Roll and Rolling Stone magazine's list of "the 500 Greatest Songs of All Time". It was also a top 40 hit. The song refers to dancing as a path to freedom: the "dancing" can be seen as metaphoric, though. The song's title most likely refers to the line in the Pledge of Allegiance "One nation under God". "One Nation Under a Groove" was released as a single and reached thirty-one on the Billboard Club Play Singles chart. It has endured as a dance funk classic and is probably Funkadelic's most widely known song. "One Nation Under a Groove" peaked at number twenty-eight on the Hot 100 and reached number one on the Billboard Soul chart for six weeks, the longest of any number one single released in 1978. "One Nation Under a Groove" became Funkadelic's first million selling single, as well as the third million selling single for the P-Funk organization overall.
