@blueveinedthrobber,
That's an awful lot of post forgetting the guy I would give the top two "funkiest songs ever".
Stevie Wonder.
All day sucker wins on the cosmic slop funk, and Maybe your baby takes it on the swampy, sticky, stanky, baby makin' funk!
I also saw no mention of Parliament's "Red-hot Mama". Cocaine is a hell of a drug... (The song, not the posters here.
Some honorable mentions can go out to Bill Withers, RHCP, and J5.
