The Beatles' "Help!"

This is pretty obvious, but I'd never noticed some of the elements that emphasize the "down-ness" in the line "Help me if you can, I'm feelin' down" in the Beatles' "Help!"  The "down" itself has a melisma where the later syllables are lower than the first, so the word itself is falling down, and after that line, there's a descending phrase in the guitar part.
