Of note: What I call the pre-chorus could be argued as NOT being a pre-chorus...But then I wouldn't really know what it is. It doesn't strike me as "part 2" of the verse--it strikes me as its own unique section--but you could argue that the pre-chorus doesn't start until that Cmaj7 chord comes back ("Say you'll always be my baby"). So is it a post-verse? A pre-pre-chorus? Idk. But for the sake of clarity I'm calling it a pre-chorus.
