Apologies, I have no idea how "perfect" perfect pitch is (is it sub-semitone accurate?) but could it be you were first exposed to these songs on PAL-region TV where they suffered from PAL speedup (or the inverse)?
No - I mean I’m listening to a song and I go to the piano to play along with it. The first note I play is sometimes a half step off.
This is not likely to happen with a recording of the instruments I’ve always played (piano and trumpet) but might happen if I’m listening to guitars or organ.
