Query: fake 60s music

You cannot separate this year from the incredible rock music that helped define it, yet what you get in this so-so documentary is fake 60's music that is meant to sound like it comes from 1968. I don't know why actual songs from 1968 weren't used - the History Channel didn't feel like paying for the rights? - but for me it really hurt the production. I kept getting distracted and annoyed by the imitation rock music. It was particularly aggravating during the part of the documentary that was specifically about the bands that were making waves at the time!
