I don't recall any teen female before Aaliyah in the early or mid 90's to be a force in the R&B world. Was there anybody who came before Aaliyah?

Age Aint Nothing But A Number: May 1994
Brandy( self titiled album): September 1994

Aaliyah was out before Brandy sweetheart....

I said "TEEN"

Those girls were well over 25 -30 something in the 90's

No, Brandy was.

I think so.

But Brandy Came into the spotlight in 1993.

.....

Aaliyah and a few months later Brandy.

Janet was in her late teens with Control.

Yes

Was Janet a teen in the 90's babe? No.

and was a nonevent until the late 90s. Meanwhile, Brandy was the "IT" girl throughout the 90s

Brandy stormed Aaliyah the minute she came out.
