You made his point. Good lyrics are hard to come by, and matching them to good music is even harder. I agree with this guy. Today's music is mostly junk in my opinion. It's hollow...Not memorable etc...It's why the groups like the Beatles and Stones are/were so great. Hit after hit after hit. That's not happening today. Not even close.
And all the really good stuff was in the 70s and very much all influenced by the Beatles. It was a Renaissance, that time period.
