My mother's favorite scene in all of video games is that j-pop scene.
I agree with everything you said of it and think of the times I've sat nearby when she's replayed the game and that scene with something almost disdainful even though I greatly love that my mother likes JRPGs.
My favorite scene in this, bar none, was when The Rock and Jason Statham re-enacted scenes from Hell in the Pacific set during the American war of independence for whatever reason.
EDIT: Ranking of the Furious: 5>6>3>2>8>7>1>4. The only ones I wouldn't rewatch in a heartbeat are 1 & 4, both being fairly boring and unremarkable nonsense rather than the remarkably nonsensical non-stop action of the other parts.
