Wholeheartedly agree with Bill. But I think that applies to all the girls (to different extents). There is absolutely no way to sell an album without a hit single, though in the absence of a hit single some girls my sell better than others. Reality is, Rihanna hasn't had a flop era yet, so I can't really judge where she sits on that spectrum, but yes, Rihanna, like others, album success is heavily influenced by the hit single.
Good thing for her that she can **** out a hit single on the regular, unlike some others.
