I do feel the pull to look back fondly on stuff I heard in my teens though - I’m in my sixties now so the late 1960s would have been ‘my time’, and as an example I love the late Beatles albums but wonder how much of this love is due to my recognition of their music and how much to the age I was at the time. I suspect I’ll never know.
A friend, who’s in his fifties, recently said to me “be honest though; the best music is from the ‘seventies” which kind of supports the theory in the op’s video. Said friend likes music but not to the extent that I do, and as far as I know has only ever attended two concerts, so he’s more like the average person than I.
I guess it should be remembered, though, that we on pfm aren’t average, so the video could be very truthful indeed for many folk out there even if not so much for those here.
