The more unknown and underrated or overlooked, the better. Must have a sort of funk about them. Makes mama wanna dance, or at least do a kind of sexy little shuffle thing.
Songs I'm thinking of are like this:
INXS - What You Need
Stand Back - Stevie Nicks
Tainted Love - Soft Cell
Safety Dance - Men At Work
What I Am - Edie Brickell & New Bohemians
