wow - talk about a Sophie's Choice. it's too hard to boil this down to one. so i'm going to break the rules and list a whole bunch! lol

My Fav - You Can't Hurry Love. frankly it's my favorite song by any group, from any time

Pure Classic Motown - probably Back In My Arms Again. that driving beat is just soooooooo motown

Most iconic - Stop

Best by each lineup:
DMF - YCHL
DMC - Love Child
JMC - Stoned Love [[although Ladder is a very close 2nd)
JML - I Guess I'll Miss The Man
SMC - not sure, since i don't really love either of the singles and i think of Walking as a MSS track. so i'm going with an album track You Can't Stop A Girl In Love
MSS - Let Yourself Go

Best song for singing backing vocals - Come See about Me

best orchestration - Stoned Love

singles that really should have charted higher - My world, reflections, IGMYLM, Ladder, Stoned

worst single - touch

best pre-hit single - let me go the right way
