If its lovin that you want

Wait Your Turn (one of the best things she's ever done) > Hard > California King Bed > Man Down (was this one really a flop though? I thought it was a hit WW?)

Man Down

Until pretty recently though, I always thought it smashed

Man Down > Hard > Wait Your Turn > > > > CKB

Wait your turn= Man Down>> Hard= What Now>>>You da one>>>>>>>>>>>> the others

Queens best songs flopped ..

I don't like any of these much but I if I had to pick then Man Down.

Out of these options I like California King Bed the best, but since it was a smash where I live I voted for Hard.

Hard is like one of my favorite Rihanna songs ever.

You da One.
I'm not sure whether this song flopped, but she didn't payed enough attention to it.

Man Down and WYT

EDIT: You Da One if it counts

Man Down.

I know these aren't options but I've always loved You Da One and one of my absolute favourite Rihanna songs is Rockstar 101. So.. those.
