I like the cover too.
And I actually think Umbrella could be even bigger, if released today. It's not that out-dated and that similar songs haven't really been released lately either. And as it's also very commercial, Rihanna's fame and popularity would sell the song better, and radios might even play it more, since she has truly established her status as one of the biggest radio-supported artists. And WAZZZUP that depends entirely on the criteria, on the basis of which you rate her songs.
