most people who love music are sensitive to music, even though they don’t understand it. Such people can respond to good music, and can tell good music from bad. They just can’t explain why it’s good or bad. Those girls who were screaming in the seats at the Beatles concerts didn’t know that they were responding to the chord changes and the other musical innovations The Beatles introduced, but they were. There were plenty of other cute boys with nice haircuts out there at the time, but most of those girls knew the Beatles were better, even though they couldn’t explain why.

The problem is, after the Beatles introduced those innovations, everybody else copied them, so if you listen to them today for the first time, you’re going to think “I’ve heard this before .” again, you don’t have to consciously know what it is you heard before, and especially what wasn’t there before you were born, to have that response.
