Apocalypse Now, if nothing else, introduced “Ride of the Valkyries” to most of my generation. Mind you, most of the guy were too busy gizzing off to the Swell Battle Scenes. :rolleyes:
I associate “Yakety Sax” with Benny Hill. That is not a bad thing.
One day, I realized that one of Benny’s other signature tunes is a speeded-up version of Beethoven’s “Für Elise”. That’s a little weird.
I can’t hear “Kalinka” without a hockey game. 
Some more sports-related ones, for me:
“Sirius,” by the Alan Parsons Project (an instrumental which segues into “Eye in the Sky”) is linked to the Chicago Bulls – they used it during player introductions during the Michael Jordan / championship era (and, as far as I know, they still do).
“Kiss Him Goodbye,” by Steam, is linked to the Chicago White Sox, who’ve played the chorus of the song since the 1970s when the opposing team removes a pitcher.
“Chelsea Dagger,” by the Fratellis, is linked to the Chicago Blackhawks, as it’s been their “goal song” for the past decade or so.
“Bang the Drum All Day,” by Todd Rundgren, is linked to the Green Bay Packers, as, since the late '80s, they play the opening of it when they score a touchdown.
And the theme to “The Good, the Bad and the Ugly” for The Ramones. Didn’t know that Metallica stole that idea. I probably did at one time (saw them twice) but it’s no longer in my memory banks.
Another one I remembered:
“Every 1’s a Winner,” by Hot Chocolate, always makes me think of the TV game show “Family Feud.” When the song was popular in the late '70s, one of the local TV stations in Green Bay used the song in an ad they produced, to promote the syndicated version of that show.
I believe newly-selected HOF reliever Trevor Hoffman did it first.
Stealers Wheel’s only hit, “Stuck in the Middle with You” is always going to be associated with Reservoir Dogs. Wikipedia lists a number of other media creations that pay homage to the song being used in the particular scene that it’s in.
Recently the song that I had always thought was called Ragtime and had always assumed was written as the theme song for The Sting was played by a player piano in Westworld. With some googling I found that it was really called The Entertainer and was written in 1902. It’ll always be the theme for The Sting to me, though.
This may venture into TMI territory, but the entire album of Dan Gibson’s “Celtic Awakening” reminds me of being in the shower with my most recent girlfriend.
Any time I hear a slide whistle I think of a penis getting erect.
That’s the first one that occurred to me, too.
“Three Blind Mice” also makes me think of The Three Stooges.
“Is that a Slide Whistle in your pocket, or are you just happy to see me?”
“Mr. Sandman” and Halloween.
Baroque Hoedown by Perrey and Kingsley is the theme song of Disneyland’s Main Street Electrical Parade (1972) and later parades.
When I was in junior high school (grades 7, 8, 9) the 3-minute time between periods was indicated by the playing of top-40 radio on the public address system. I didn’t listen to popular music at that age, so all my knowledge of that musical era (1981-1984) is in three minute bursts.
There are lots of songs that bring me eight back to hustling from one class to another on junior high. I can’t name them all but the most memorable one for whatever reason is Michael Jackson’s “Human Nature.”
“I Only Have Eyes for You” by the Flamingos is linked to the episode of Buffy by the same name.
The Toreador song from Carmen will always be the Palm Dairy Products song to me first, and the Gilligan’s Island Hamlet “Neither a borrower nor a lender be” song second.
The song “Lavender” by Marillion will always remind me of Angus Deayton from “Nighty Night”.
Theme from 2001: A Space Odyssey
I was required to memorize Verdi’s “La Donne e Mobile” in college for a class. All I remember now is the first verse. After that, my mind automatically switches to Voyager’s EMH singing the rest.
