Big name collaborations

Recently, the big news was the collaboration of Zedd and Selena Gomez; then the gossip of them even being a couple. Now Diplo made a few confirmations at the Grammy's to clear up some rumors. It seems he is indeed in the works on the new upcoming Major Lazer album, and some big names were dropped - Ariana Grande, Ellie Goulding, Travis Scott, Pusha-T, and Gwen Stefani. Is this a new poppy twist that we may see reappearing in the electronic world? And is it for the better, or will things go more pop and  "main stream" oriented?
