I do not disagree with you in regards to the ethos and the meaning behind it, and, to me, that makes the funk in it even more poignant. A quasi-nihilistic “your soul’s a husk anyway, so you might as well get groovy,” with the added tinge of still having a husk for a soul.

Dunno how to explain this any better, although it’s one of my favourite nuances in Sad Music in general.
