Even though "Roar" hit number-one and "Bad Romance" hit number-two, I think "Bad Romance" has a bit more longevity. I still hear it more than I hear any other Gaga song on the radio, and it's easily her best song and most iconic. I think "Roar" is a bit overshadowed by Katy's other hits. It wasn't that big of an achievement for her because it was her ninth number-one, whereas "Bad Romance" quickly became a huge song for Gaga.
