The people i showed all of the ARTPOP songs too LOVED Aura, Swine, ARTPOP, and MANiCURE and Applause. They said Sex dreams was alright but the wouldn't be in a rush to listen to it again. They all hated Jewels and drugs. Personally I think that MANiCURE, Aura, or Swine would be perfect singles :)
I loved every song she played at iTunes except Aura. The chorus was catchy but the beginning and verses were just not doing it for me - the arrangement and way she sung them, not necessarily the lyrics. LOVE Manicure - my favorite by far! Jewels and Drugs blew me away! Was NOT expecting that and I loved it! Applause just gets more and more awesome every time I hear it. I am really excited for this album overall.
