It will be terrible if not tbh, she's the Queen of Pop
She's already sold 10x as many albums as your fav and she is gonna earn more money from the tour than what Gaga earned from the ARTPOP era, not too terrible.
It could because it's better than both ARTPOP and Madonna's latest two releases, but I'm not betting on anything since MDNA sold extremely similar to ARTPOP and we have yet to see whether the Rebel Heart release strategy and the Grammy Awards will replenish public interest in Madonna.
