I have the predecessor of Mrs. Gaga at home and found the songs really well except for a few exceptions. But when I listened to artpop, I just thought ... omg what a crap! So I listened to the album several days in succession repeatedly - and I regret to say, I stick to my first impression: artpop I find horrible!
I think only 2 songs really well - at the rest I had to at least 1: 50min turn on because I did not take it anymore! Sounds to me all too much like Trashpop too much dance ... no song remains except in my ear: Applause Sexx Dream
