I mean, it's been about 5 years since the song has been released, and the whole world still knows it. You can still hear it on the radio from time to time, and who could forget the "curse" Rihanna put on the United Kingdom with this song

It's undoubtedly Rihanna's biggest hit, and without it, her career just won't be the same. So tell me, IS Umbrella a classic?
In my opinion, I think it is. Obviously it's not a "BOMT, Thriller, Vogue" type of classic, but still a classic.
