I have noticed the issue with stressed syllables over particular notes over the years. Part of the issue is the fact that, well, most pop songwriters beginning in the rock era did not approach writing lyrics with the level of care that, say, Noel Coward or Larry Hart did (That's Larry Hart, not Kart). I know this is a gross generalization, but even some of my favorite lyricists of the rock era, like Ray Davies, are capable of sloppiness or tossing off a throwaway line between two brilliant ones.
That said, I think Andy Partridge of XTC is a brilliant songwriter, and I think he deliberately offsets the stressed syllables and stressed notes to create tension in some of his songs.
