I thought this was gonna be a thread on who is the better vocalist......sis....
Anyway, I choose Mariah simply because she's impacted R&B
and Pop. But of course, ATRL will say Britney. Mariah's more successful. And 'We Belong Together' pretty much has had more impact than anything Britney ever put out (besides BOMT). And that song was in Mariah's late 30s. Britney could/would NEVER. And isn't 2013 Mariah's 25th year since releasing her debut album? I honestly can't picture Britney still releasing music in 2024. Sorry.
For some reason, ATRL thinks that people on this site represent the GP.
