I want to know the answer to the following question:
What type of adult contemporary music was popular in the 1960s?
All the background I'm provided with is that "Adult contemporary music (AC) is a style of music, ranging from 1960s vocal and 1970s soft rock music to predominantly ballad-heavy music of the present day, with varying degrees of easy listening, pop, soul, rhythm and blues, quiet storm, and rock influence.". Is that enough to answer the question?
