But let's be real who would actually know the lyrics to Bad Romance if it played on the radio right now? Bad Romance won awards but everyone was on the "I Love Gaga" bandwagon back then. TiK ToK will be remembered more than Bad Romance in every way: the lyrics, the production, her image.
Of course Gaga has more memorable songs, but Bad Romance is not one of them. If this was Poker Face vs. TiK ToK or Born This Way vs. TiK ToK it would be a whole different story.
