well Gaga is not one to follow the trends like the other girls so I don't think she'll be popping out ballads
You and I was a hit in the US so that proves she can have a non-dance-pop hit, it was a COUNTRY rock n' roll ballad which is only welcomed in America, hence why it didn't do well WW.
producers like RedOne are the ones who are in their way out but Gaga is working with fresh producers like Zedd and Madeon so she'll be fine, plus there have been EDM hits this year like IKYWT, Scream and Shout and DYWC.
