Flo Rida's sole role is spacing -- he's the gap filler you wait through patiently for the Good Bit to come around again.

So it was with Etta James on "Good Feeling" and so it is again with Brenda Russell on "I Cry"

 

Because you can't just repeat the Good Bit over and over...  it would get wearing to be blissed, euphoria-wracked without a break.... A climax only makes sense if there's a plateau between it and the next peak.

It's not an ignoble function in pop life, Flo Rida's. It's like being the layer of sponge in a cake. Nobody would want to eat a cake entirely make of the frosting.
