I do not like Aura. Hate it even more for being the opening the album. It's only purposes are to say "do you want to see the girl behind the aura" as in the real Gaga and to have the phrase ARTPOP be muttered in the first song in addition to the middle song (ARTPOP) and the last song (Applause).
Liked it a lot at first, but I feel like it's a novelty song and the novelty has worn off for me. A decent track, but definitely in ARTPOP's bottom 3 for me. The chorus is still killer though... she should've ditched the dicey appropriation altogether to make the song stronger. Demo verses are better.
I love the demo, the intro is amazing to me, so are the verses and the chorus is one of her best ever. Aura is definitely an amazing track and one of the best Gaga has created, the album version is a mess though.
I'm honestly shocked that more people liked Venus than Gypsy!
But it still doesn't change the fact that Gypsy is better off being the next single anyways.
