Applause, yasss
I also agree that it grew on me. I was not into it as a single or anything at first, and ha vocals in the first verse were very off-putting. Then all of a sudden I was getting into it.
The only thing I can disagree with is it being at the end of the album. I always get a biT pressed with Godpsy ends and then Applause's DO DO DO DO DO DO begins. It breaks my heart.
