I started a thread here a year or more ago on this subject. Damned if I can find it now tho
But it sure had "Movies is Magic" by Brian Wilson, and "the Film of My Love" by 10cc from their album The Original Soundtrack.
"Rock on" by David Essex is another that refers to James Dean. I'd also call "Candle in the Wind" by Elton John, a film-referencing song.
Taco has a great song about Valentino on the "After 8" album.
Quite a few Bowie songs have film references.
Several posters back then were quite keen on "Dinner and a Movie" by Phish, but I've never heard it myself.
Good luck, I'd love to hear your final tracklist.
