Growing up, I never heard a song recorded before the ‘50s in public or on the radio, but heard mainstream ‘70s music almost exclusively through to the early ‘90s. These days, I hear almost nothing older than about 1975 in mainstream culture, with a few specific examples (Beatles, Zep, etc.)
The tragedy: there’s almost 100 years of recorded music from before 1975 that we rarely hear anymore in public. Popular culture seems to think culture started in the ‘70s, like when I was a kid and popular culture seemed to start in the 1950s.
The past is interesting. Why don’t we share it, pop culturally, with the world at large?
