Musically, Someone Like You is the best out of these. But I still voted for it because it annoys the crap out of me and is overplayed so damn much. I just..can't at this song anymore
Bad Romance is easily the most overrated song on here (and on the Internet as a whole). But Bad Romance isn't overrated in real life, as I honestly haven't heard anybody talk about the song since 2010 outside of the Internet.
And We Found Love should be on there for Rihanna's song. What's My Name? isn't overrated. It's one of the best songs of 2010 imo. The people that hate it are the ones that like nothing but dance-pop music, so they don't like What's My Name? since it has a different rhythmn (similar to RnB music, which they think is boring): http://www.youtube.com/watch?v=CXsT_THgy9Y
