I'm obsessed too. Just can't help it! Radio sucks and I think its really changed since I listened to it regularily. I was watching an info commercial last night about sixties music. You know, the Time Life collections. Back then the radio played everybody. There were hundreds of bands. Between the British invasion and US music, the variety was amazing. Groups, duos, single artists of all genres. It was an amazing time in music.
Top 40 Radio was pretty bad in the 60's -- and worse in the 70's. The difference was FM radio was not controlled by programmers in the late 60's and first half of the 70's. Now there is internet radio serving the same function.
Here are the BB Top 20 songs from 1970 (based on radio airplay):
I love a few of these songs, like many, can sing every line of all of them. BUT IMO these radio hits were not the best music of the time.

This top singles had little to do with the best albums of 1970, which were also all best sellers ...
Neil Young "After The Gold Rush"
Led Zeppelin "Led Zeppelin III"
Black Sabbath "Paranoid"
Van Morrison "Moondance"
The Stooges "Fun House"
The Velvet Underground "Loaded"
Crosby, Stills, Nash & Young "Déjà vu"
Creedence Clearwater Revival "Cosmo's Factory"
Santana "Abraxas"
All Things Must Pass
George Harrison "All Things Must Pass"
James Taylor "Sweet Baby James"
The Man Who Sold the World
David Bowie "The Man Who Sold the World"
Elton John "Elton John"
The Kinks "Lola Versus Powerman and the Moneygoround (Part One)"
Joni Mitchell "Ladies of the Canyon"
But you could hear album tracks from these albums on the the great FM stations of the time -- like WMMR in Philadelphia.
ETA: Elton John's first #1 hit and US Platinum song was not the beautiful "Your Song", it was "Crocodile Rock".
