I wouldn't count it as rapping. The delivery reminds me of--something--but I can't place it. Maybe it was some song about the 1980s that I used to hear over the speakers at my gym, but I can't recall that either, and I'm certain I never knew who did it. It's almost like some sort of chant until he gets to the chorus.
Well, that's kind of what rapping is like -- saying rhyming phrases tunelessly between choruses -- right? Some rappers are more tuneless than Michael Stipe, but then all other REM songs have tunes, so it's a novelty for Stipe. Eminem can chant even faster than Stipe does in ItEotWaWKI.
I do think there's a diffaerence in rhythm or beat, but I don't really understand that stuff. Someone more familiar with rap might ....
... OK, I just texted one of my sons. He said: "I feel like just stylistically it doesn't really fit as rap." That seems true, if a little lacking in definitiveness. Certainly the subject matter and kinds of things they talk about are different.
