So after Miley left the music industry and Demi's new era was a completely non-event/flop, are Ariana & Selena the only relevant people left out of the newest generation of Pop Music (this doesn't include Taylor etc)?

It used to be Miley vs Demi vs Selena vs Ariana, but now it looks like Selena & Ariana are the ones with the most potential because of their great team, producers & their material.
