It's not up for discussion

Madonna's songs are so much bigger hits, they've sold so much more, charted highly in so many more countries....stats on new streaming services are not the end-all of what is more popular. If Mariah's songs were bigger and better remembered she'd have a bigger career. If she had bigger hits, then she'd have had bigger hits. She doesn't. She didn't. The end.
It's embarrassing to be arguing otherwise when the moose can't tour and won't outsell MDNA's first day sales with her total.
