well I think it depends on how you read his original post/question.
They are asking about Soundtracks, not scores, and he specifically mentioned this : "Preferably with songs that have been around for awhile and weren't memorable till you saw it in a movie"
So that would mean to me a soundtrack with lyrical content versus just a score.
Most of the iconic movies you mentioned are scores so I wouldnt have answered with here but a few would be on my scores list.
Danger Zone, You've Lost That Loving Feeling, and Take My Breath Away fromTopgun would be on my Sountrack list. Unchained Melody too, St Elmos Fire... probably a few others if I thought about it. Couple songs from Batman in the 90s. Blergh, pulling a blank cause its 130 am lol
