I changed my mind again. “Rave On” by Buddy Holly. GOD, I love that song!
Born to Be Wild by Steppenwolf. Charted number 2 on US Billboard Hot 100. Came out in 68. I was 5.
There are three or four to consider, but ultimately I’ll go with the second greatest feel-good song of all time, which came out in 1966, a year after I was born.
From the 1987: “Faith” George Michael
I’m not going to overthink this. I’ll just go with “A Day In The Life”.
1970’s: “The Ballad of El Goodo”, Big Star.
The adrenaline kicks in like nothing else when Gonna Fly Now starts.
1970’s: Nobody’s Fault by Aerosmith. One of the greatest songs of all time that I NEVER hear anyone talk about.
“London Calling” by the Clash.
Today I’ll choose Ode to Billie Joe.
Sixties of course.
1960s: so hard to pick, but Surfin USA
1950s. I just looked through a list of 1950s songs at the (English) NIM site. Three that looked good were:
Dream – Everly Brothers
Sh-boom. – The Chords
Take Five – Brubeck
Let’s go with Phil and Don.
The live version of The Velvet Underground’sWhat Goes On seems to me to sum up the late 1960s - the guitars chugging on relentlessly and the organ almost but not quite spiralling out of control…
60’s
Youngbloods - “Get Together”
I was born in the sixties. Tough question because I’m not a big fan of sixties music. But the thread rules say pick one so I pick Eleanor Rigby.
I really identify more with the seventies. And there’s no contest which is my favorite: Hotel California.
Hard choices from the fifties but I’m going to have to go with Jailhouse Rock.
I was born in 1970. Depending on whom you ask, I was born in either the 60’s (the literalist/scientific angle) or the 70’s (the colloquial angle). I’ll take the colloquial:
Dust in the Wind, by Kansas.
1960s. A tie between the Beatles “A Day in the Life”, Rolling Stones “Sympathy for the Devil”, and “Heard It Through the Grapevine” by Marvin Gaye.
Damn, the 60s were great for music!
1968/69 Crimson and Clover. by Tommy James and the Shondells my first ear worm, getting ready for the 1st day of 1st grade, the kitchen radio tuned to WQAM. I missed the bus home that day, a nun drove me home in her Buick iirc 
crimson and clover over and over
Moonlight Serenade
