Most underrated / underappreciated Motown Disco 12-inches?

[Ngroove]

As a twenty-six year old Motown nut, whose spent my past ten-and-a-half years previous collecting Motown through CDs [[proudest centerpiece, I would say, would be my Complete Motown number ones ten-disc set with the box modelled like the Hitsville USA), as of last Christmas, FINALLY GOT A RECORD PLAYER, WOO!

Now, no music, no matter how obscure, is out of my reach, as long as I could find it off of second hand stores, flea markets, or online stores hahaha!

So - Motown-maniacs out there, name off some great listens, from 1972 to 1987, those songs and artists whose sounds just as great, danceable, and most importantly, funky, as the real hitmakers of the time - Eddie Kendricks, Stevie Wonder, Diana Ross, Jackson Five, Commodores, Rick James - just the tragic facts that negligence and underpromotion never got them the recognition, airplay they should get?
