Parochial.
Music from 20s 30s 40s 50s and 60s are great and have been popular.
Only the uneducated are not familiar with them.
The American song book goes back even further. And show tunes? Wow!
To think the world begins and ends with the tastes of the boomers?
As I said. Provincial.
Dry up. I made it clear I was only speaking for myself.
1. Almost all generations think the music from their teen and pre-teen years is the best music.
2. We may be talking about classic pop/rock music (say from mid 70's to mid 90's -- the Generation X era) is simply better. I say that because it's not just Generation X that knows all those songs and loves them, but their kids and now grandkids. I dare say the younger generation knows those songs way more than us generation X'ers knew songs from the 1960's and 1950's, etc.
3. Don't underestimate the effect of marketing to the generation that makes most money. The baby boomers are retiring now (less income, less spending). The generation X and younger generations are working, but of the generations still working, generation X is the one that's advanced in their careers (making the most money). So a lot of marketing is steered to that generation. That's why so many movies and commercials have 1980's rock n roll and such -- appealing to the generation with the most income. I think that keeps that era of music more prevalent (keeps that music in our heads for more years and the younger generation can't help but be exposed to it a lot).
