You said: "To provide some perspective: A young person in 2022 saying they enjoy listening to The Doors’ “Light My Fire” (1967) is equivalent to a young person in 1967 saying they enjoy listening to Al Jolson’s “You Great Big Beautiful Doll (1911). Around 55 years between each."
You are technically correct about the years difference between the songs you have used in your example but don't really take into consideration the explosion of different genres that took place in the 60s and 70s that would give a young person of today many more options to find something they like. Popular music of 1911 was either Ragtime or somehow related to Ragtime, Classical, with Jazz and The Blues just getting started. From its start in the 50s, Rock and Roll exploded in the 60s, while Pop, Jazz, R&B, Folk, and Classical continued strong and sub-genres of rock like Metal, Acid, and Progressive were all getting started too. There was just way more diversity in the 60s and 70s making it much easier for anybody of any age to find something they like. If someone doesn't care for Ragtime, it would be difficult to find them liking much of anything that came out in 1911. So while you're correct on the time differences, it goes a little deeper than just saying they're equivalent.
