Plastic soul

Plastic soul is a description for soul music that is believed to lack authenticity.
Origins.
Paul McCartney referenced the phrase as the name of the Beatles 1965 album "Rubber Soul", which was inspired by the term "plastic soul". In a studio conversation recorded in June 1965 after recording the first take of "I'm Down", McCartney says "Plastic soul, man. Plastic soul." 
Usage.
David Bowie also described his own funky, soulful songs released in the early to mid-1970s as "plastic soul". These singles sold well, and Bowie became one of the few white performers to be invited to perform on "Soul Train". In a 1976 "Playboy" interview, Bowie described his recent album "Young Americans" as "the definitive plastic soul record. It's the squashed remains of ethnic music as it survives in the age of Muzak, written and sung by a white limey." Bowie's most commercially successful album, "Let's Dance", has also been described as plastic soul.
