Listened to that Taylor Swift song over lunch to remember what my brain had blocked-out, no doubt in survival-protection mode.
Utee is indeed correct, most everything except the chorus has some music in the background, and while it might not be obvious to some that she's "singing," she certainly is saying her words in a definite pattern of limited notes that correspond to the music in the background. I would need to listen on better speakers, but there might have even been a soft pedal-tone in the chorus.
The point of which is to say, avowed Swiftie utee94 clearly planned this whole thing to make me listen to a piss-poor song, and he is a dick.
