I wouldn't call them unpopular but they're certainly not "When Doves Cry" or even "Girls & Boys". Most of you devoted Prince fans probably know 'em by heart but let's just say songs that a person surviving on the Hits CD's wouldn't know:

-Pink Cashmere
-Love 2 the 9's (I really love the first part)
-4ever (the lotusflow3r track that generated virtually no attention, positive or negative)
-Do It All Night
-Rockhard in a Funky Place
-Le Grind
-Cinnamon Girl
-Forever in my Life
