Aha! That's true. And likewise, the guy who slept through Dylan's performance of "Like a Rolling Stone" and attached no importance to it may very well have been affected by it also in some way, because the greater society around him was. We are all affected by cultural changes, whether or not we give it conscious recognition. There is no question that we have all been affected by Elvis, Buddy Holly, Bob Dylan, the Beatles, the Stones, Hendrix, Joan Baez, etc...

This does not necessarily mean that we are conscious of how we've been affected though, does it? Nor does it mean that we must like that music. I sometimes think the people who are most affected by a new style of music are not just those who like it, but also those who don't. I remember older people in the 60's who were positively obsessed with the Rolling Stones. They hated them. Those people were profoundly affected by the Rolling Stones. I wonder if they learned anything useful from the experience?
