I for one never understood everyone's dislike for it. Yes, it may sound out of place in ARTPOP, but it's one of Gaga's best ballads (next to Speechless).
They probably just love it because Rick Rubin's name is attached, but stan.
I can imagine the Rick thing has a lot to do with this because this song is really a mess. I feel like it tries harder to be emotive than it actually succeeds at in execution.
