and then Mariah wasn't even on the full-throttle Katy and Rihanna are.
Mariah's 18 #1's are not her full potential, if her label was desperate as Gaga she could've had 23+ #1's.
"Can't Let Go" was #2 on Hot 100, but they took it off shelves because they wanted the album to sell even more, so it didn't go #1.
"Loverboy" was #2 on Hot 100, with a clear shot for #1 but Mariah's exhusband (head of Sony) purposely discounted Destiny's Child's single to block her.
"All I Want For Christmas" was #14 on Airplay when it came out, and they never released it Physically so it never charted. They had "My All" go #1 even though it's Airplay was #15 the week it went #1. If they would've tried, AIWFCIY would've gone #1.
"Forever" was an album track, and charted #12 on Hot 100 Airplay. A single release would've been an easy #1.
