Tarantino, as well as Cameron Crowe, are great at picking great songs for their soundtracks.
But the song that will never be the same is “American Woman” after the 2nd Austin Powers movie. Lenny Kravitz didn’t change a word or a note, but it now looks and sounds like it pro-American girls instead of the insult Randy Bachman et al originally wrote.
Not a song, but I’ve cracked up a few times recently when I’ve noticed people in coffee shops drinking coffee and smoking cigarettes ala Coffee and Cigarettes.
Or at least made it spin around a few times.
Yes, but Ghost completely obliterated their “Unchained Melody” for any other purpose.
Also, Bob Seger’s “Old Time Rock and Roll” is pretty much forever attached to the iconic Tom Criuse-dances-in-his-briefs scene from Risky Business.
It always makes me feel really tense and on edge after they used it in the last scene of “The Sopranos.” I love it, but I associate it with the ultimate cock-tease.
I can not hear Dropkick Murphys “Shipping up to Boston” without picturing Leonardo DiCaprio in “The Departed”. Yummy.
…or candy.
“Hip to be square” by Huey Lewis and the News from American Psycho. Made the song a bit better in a way.
Damn you, panache! Exactly the one I was going to post. Oh, well.
Peter Gabriel’s “In Your Eyes” cannot be heard by me without pitcuring John Cusack standing outside in the rain holding a huge boombox over his head.
I havn’t ever liked “The Old Main Drag” quite so much after having it forcefully merged with the shitty Keanu Reaves in the horrible,cloddy “My Own Private Idaho”
It isn’t a Vietnam War movie without a slow motion helicopter sequence with Rolling Stones Gimme Shelter
…shouting “Stella!! Stel-laaaaaaaa!!!” 
At the end of Dr. Strangelove, with all the bombs dropping and mushroom clouds billowing while Louis Armstrong sings “What a Wonderful World.” That gravelly, happy voice is now the voice of the Apocalypse.
In an episode of My Name is Earl, they play ZZ Top’s “Legs” as Joy’s stomping out of the store that refuses to refund her $3000 for a wrecked entertainment system she stole in the first place. Even though she’s angry, she still struts like she owns the town. She passes an alleyway, is off camera for a couple of seconds, then pops her head back in and sees a store delivery truck. She’s got leeeeeegs. She knows how to use them. Mainly to keep her feet pressed to the accelerator pedal as she squeals the truck’s tires out of the alleyway.
Heh, that reminds me… Flight of the Intruder has forever linked in my head Brad Johnson and Wilem Dafoe singing (horribly off-key) “Downtown” by Petula Clark
This is the one I was going to say. Whenever I hear it I think “oh man someone is about to get their shit rocked”
I heard this song on the way home from work today and all I could think of was “Phoebe Cates topless”. It made me smile. 
Does *“The Concert for NYC” * count as a movie?
Sorry, but I can’t help bragging on The Who here. Without doubt, their set was the ultimate moment of the night. They took everyone in The Garden away from everything else in the world, if only for a few minutes. Come to think of it, isn’t that what music is all about?
“Jesu Joy Of Man’s Desiring” was ruined for me by the menu screen, of all things, of the End of Evangelion DVD. Soft lovely classical music plays while various horrible things from the movie are seen happening on the screen, and then all of a sudden, after about a minute and a half of this, with no warning, a close up on someone’s face as they SCREAM a blood-curdling scream, and then it starts over.
Whoops, I shouldn’t use the search feature when I’m tired. Sorry for the zombification.
