When I hear Orleans’ “Dance with Me,” I think of Gina in the summer of 1975.
When I hear ABBA’s “Dancing Queen,” I think of walking along a road in the West of England in the rain one evening in September 1976.
Ha! Me too. I worked at radio stations in the Northeast, the South, the Midwest, the Midsouth and back to the Northeast in a span of a few years in the 1970s. Back then, songs might be hits in individual markets but receive scant play elsewhere…unlike today where every radio station everywhere plays the same songs. "(I Don’t Want to Love You But) You Got Me Anyway" by the Sutherland Brothers and Quiver reminds me of Florida. “Doraville” by the Atlanta Rhythm Section brings memories of Kentucky. Neither were hits much outside those areas.
I could probably still talk up the intros to those songs too. It’s a disc jockey thing.
It reminds me of Duffman.
Rachmaninoff’s Piano Concerto 2 makes me think of the 9/11 attacks, because it was what was playing on the CD player at the time that I was learning the news about the attack.
The Rolling Stones’ Satisfaction always takes me back to Orchard Swimming Pool. It played over and over again on the jukebox while we were swimming. I bet the staff there went bat-crap crazy before the summer was over!
This morning I was in the grocery store and James Taylor’s “You’ve Got a Friend” came over the air.
Aside: I like to shop really early-- 6 or 7 am-- because the store is practically empty. However, the shoppers who are there at that time are usually old people like me. And the music they play in those early hours is always from the 60s and 70s-- original artists, too.
Anyhoo, that song and that album (“Sweet Baby James”) was the soundtrack of my first year away from home after college-- 1970. I stood there in the salad dressings listening and remembering my first apartment, my boyfriend who became my first husband, my job as a GTA… wow. I was embarking on a very bumpy and convoluted path, but of course, I didn’t know it.
A young guy who was shelving stuff asked me if I was having trouble finding something. I didn’t reply “Yeah, my lost youth,” but said, “I was just remembering a time before you were even a twinkle in your Mama’s eye.” Hell, it was probably before his Mama was a twinkle in his Grandma’s eye.
Whenever I hear “Sundown” by Gordon Lightfoot, I think of the movie “Jaws.”
When I was 10 years old, my parents took me to see it at the drive-in theater (possibly not their best decision–I’m still haunted by the image of the shark biting the guy in half). Before the movie started, they played music over those crappy speakers you attach to your window, and “Sundown” was one of the songs.
I have absolutely no idea why that particular song/association burrowed into my brain and took root to the point where now, over 40 years later, it’s still there–brains are weird, I guess.
More conventionally, a whole bunch of popular songs from the 1983-1984 era take me immediately back to college, hanging out at friends’ apartments an the university union. Even if I don’t like the particular song, they still make me happy because that was one of the happiest periods in my life.
“Hard for Me to Say I’m Sorry” by Chicago reminds me of waking up in the morning with that song playing, and hearing it for the first time. I must have been in middle school, because it was in that particular apartment, and it was playing on a giant radio that had an 8-Track player on it.
(“Let’s Get It On” by Marvin Gaye reminds me of the King of Queens episode where Deacon and Kelly played it every time they started knockin’ boots in their room at the resort - and Doug and Carrie heard it start up over and over and over, and marveled at their friends’ stamina! 
)
“Make Me Smile” by Chicago was a real popular song here when we graduated and were just starting our careers, seriously dating, leaving the nest to live on our own. The future was wide open, straight ahead, there were jobs galore, and we were pumped. Whoever would have thought the world would have become such a shit show for our own kids, years later…
“If You Love Me (Really Love Me)” by Brenda Lee reminds me of the first time I heard it-- after the Loki episode in which Loki gets pruned.
Babe by Styx reminds me of my first heartbreak. My high school girlfriend of two years decided to move on, and she broke my heart. Crushed it. The opening of the song, that keyboard intro, reminds me of the tears I wanted to cry. That was in late 1979 / early 1980, and today when I heard that song I still feel a twinge of that pain in my chest.
A couple of weeks after she broke up with me, I signed the military contract and was shipping off to boot camp.
When I hear I Wanna Hold Your Hand, I keep thinking of the Christmas after JFK’s assassination, and how the US was trying to heal.
There are a few songs when I hear I can only think about Weird Al’s parodies of them…
“Jeopardy” by The Greg Kihn Band----“I Lost on Jeopardy”
“The Safety Dance” by Men With Hats----- “The Brady Bunch”
among others.
Oh yeah, he’s improved a lot of songs for me too. 
When I hear the Beatles’ Yellow Submarine it takes me right back to being 12 and away with my parents on holiday, and being allowed to go with them down to the hotel bar for a pre dinner drink, and that song seemed to be always on the radio in the bar. I felt so grown up. And I also developed a massive crushon one of the Italian waiters in the hotel restaurant. Oh Roberto!
