You're skipping a couple generations there. That's acceptable.
Ever since the first beginnings of a "pop youth culture" - usually associated with the mid 1920s in the cities, as middle class young people embraced jazz, nightclubs, dancing, etc. - the pattern has been:
Your music is the real stuff.
Your parents' music is horrible cheesy and square.
Your grandparents' music is quaint and interesting.
Your great-grandparents' music is the real stuff, from a different era.
The current day is the first since then where a significant fraction of younguns are listening and actively seeking out the music of their parents' youth.
Of course there have always been outliers and musicologists; witness my high school friend who in 1978 was a HUGE Johnny Mathis fan. But he was one in a thousand, I assure you.
To be fair, my folks were born in the 50s and listened to classic rock, I can probably find all my dad's CDs I stole from him in my music collection still, from The Police to Keith Jarrett solo albums, the Bee Gees
My generation is a special case though, our parents' generation in my opinion was the most prolific for amazing, immortal popular music.
