"influence on her" - by going to the EDM/dance route? Working with the likes of Calvin, Diplo, Skillex, Zedd, David Guetta, etc? I don't think Taylor needs to do that when so many pop artists are already doing that. I think the next move, after releasing another pop album, is going the pop-rock route and be more instrument based, since she can play the acoustic and electric guitar. Not a lot of pop stars are playing their own instruments right now. So in terms of people she's hanging around who might have some influence on her, I'm hoping she'll lean towards Haim than Calvin.
The EDM/dance route is very diverse and always changing. She could pluck an up and coming underground DJ/producer and bring something to the mainstream that isn't quite as popular yet.
But other than a few songs and some remixes, I agree the EDM/dance route isn't quite right for her. I think for the next project, she can afford to take more risks and stretch herself outside of her comfort zone a bit. She shouldn't be looking to do 1989 2.0.
