Although it’s an old song and wasn’t written for this movie, I’m sure they chose it as the stalker’s song for the lyrics, especially this part...
“Can’t you see that you’re leading me on?
And it’s just what I want you to do,
Don’t you notice how hopelessly I’m lost
That’s why I’m following you.”
yep- it works- that part kinda reminds me of glen close psycho scene with michael douglas for some reason-
