CMM is more successful than any Beyonce's songs, but there's nothing about it is iconic at all.
I've always tried to find out why people say it's iconic and I always failed to find one.
CMM has become iconic because of it's sales, longevity and extremely popularity. All the videos and memes that arose from CMM is on par, if not greater than SL. "So here's my number, so call me maybe" >>>> "If you like it than you should have put a ring on it."
