I want to know the answer to the following question:
Generally speaking, what percentage of music on easy listening stations was instrumental?
All the background I'm provided with is that "The easy listening format, as it was first known, was born of a desire by some radio stations in the late 1950s and early 1960s to continue playing current hit songs but distinguish themselves from being branded as "rock and roll" stations.". Is that enough to answer the question?
Answer: no
