Judass and Alejandro. She'll probably only use Applause from ARTPOP and nothing else.
I think she should take out Telephone instead. You can tell she doesn't really care for it anymore, and Alejandro has such a standout sound amongst the rest of her discog.
She should give all her singles some shine every now and then. Not only the big hits. She can give some songs a break every now and then, I also wouldn't mind her performing album tracks from other albums. I think just performing a GOOD set list each night is better than focusing on specific songs. You can't satisfy everyone by trying to cram all your singles with your new album in there, it just doesn't work.
