I think Adele will be fine even if her new album is mediocre. I'm here for an Adele/Gaga collab, though. Gaga really needs to widen her pop horizon a bit from EDM.
Ariana is living proof that the whole "TD was only successful because it was so heavily promoted" excuse is stupid (unsurprising considering only Katy haters use that excuse and I've already clocked the tea on their intelligence) The amount of promo she's had compared to her success, they're really trying to make her happen
Meghan is the American Adele. Americans are half as good as Brits and Meghan is half Adele's size, she is half as good looking she has half of her talent and her music is half as good.

Then she will have a successful career, about twice as much as Katy.
