I would yeah. She had a flop era, but artists can come back from a flop era. Madonna has done it. Kylie did it.
She will need to have a successful album again though. There is a lot of pressure on the next album. All it takes to capture the imagination of the GP is a great song. I am not ruling her out. Hopefully she can come back with an album with better songs than Artpop.
People saying ''4 years ago maybe'' or ''not since 2010'' when BTW released in 2011 sold more than your faves and her tour was more successful than your faves tours at their peaks
Yes, anyone that says no is obviously lying. She has more power/impact than all of them except Beyonce. Just because she had an under-performing era doesn't tarnish her entire status as a main pop girl.
