Not a /mu/ regular, but noticed something interesting today when listening to a classic rock station.
Back to the Future soundtrack (1985):

There's a particular, iconic musical phrase that crops up all over the soundtrack in different arrangements and at different tempos. Unless somehow you've never seen these movies, you know what I mean. In particular listen to the portion starting at 35:54.
Now listen to this (The Moody Blues - Tuesday Afternoon (1967))

4:25

Know what the strangest thing is? Tuesday Afternoon originally appeared on the album "Days of Future Passed".
that's pretty coincidental OP. It only kinda sounds like the Back to the Future theme. still pretty cool though
