Seriously, songs like Before He Cheats and I'm Yours/I Won't Give Up that had great longevity should have. They've sold a ton and were big hits but never got that close.
Jay-Z ft. Rihanna & Kanye West - "Run This Town" should've hit the top spot, to be honest. Also, Pon de Replay by Rihanna (but she was blocked by the song of the decade "We Belong Together") as well as the flawless "Don't Stop the Music."
Star Ships deserved a #1. It had amazing longevity and was blocked by ridiculously huge songs like stronger somebody that i used to know and call me maybe
