"ARTPOP" slayed me out of all of them surprisingly. It gives me Confessions on a Dance Floor vibes for some odd reason. It's so mellow yet so catchy.
"A Hybrid can withstand these things, my heart can beat with bricks and strings. My ARTPOP could mean anything."
COADF is what I thought of as well. And of all the Madonna comparisons that could have been made, I'm very glad that this is the one that's real. "ARTPOP" is perfect. I'm going to Stan for that song alone for years.
Basically, everything did.
