We are biased but I think it is hard to deny that a lot of music from those periods has aged much better than will the "product" put out by current "stars" such as Kanye, Drake etc. This comment may be attacked by younger posters but my only response would be that I feel lucky and privileged to have been a teenager in the 70's when there was so much good music released (some terrible stuff too) and bands played real instruments, singers were not auto tuned and getting together with mates to listen to a band's new release was an event.
I agree with you (completely).
Personally, I love the much of the music of the Renaissance, and adore Baroque and much classical music, along with trad, folk and some jazz.
But I will say that as someone who was also a teenager for some of the 1970s, the music of that era resonates with me (yes, agreed, some of it was atrocious, but some was astonishingly good and has aged exceedingly well) - and that of the 60s, 80s and 90s - in a way that little from more recent eras do.
In those days, music mattered; it mattered as an expression of art, and creativity, and it seemed to matter as an issue of identity, as well.
Most of my peers at school (and a surprising number at university) - both male and female - played at least one musical instrument (and some of them played very well, whereas others merely plucked, strummed, or struck), such as - mots usually - guitar, or piano, but also including flute, violin, cello, drums, and, in one instance, the sax.
