[...]"It's OK" (and calling "gotta go to it/through it/with it" a chorus is giving it a good bit more credit than it probably deserves).
Agree. If it really is, it may be the shortest in music history. I hear "It's OK" as long verse with little side verses - you know, short break with people joining Mike, then he continues "listing positives", right to the end where it unfolds to "Find a ride" tag. It's like the song paved its way to get to *that*. It isn't typical verse-chorus structure when the last chorus usually gets half-tone higher or in general slightly changed (the singer adds new notes by using vocal embellishes etc).
