Aaliyah wouldn't be where Amerie and Mya are. She was starting to build a success movie career. Romeo Must Die made nearly 100,000,000 million in the box office.

Amerie only had 1 Top ten hit
Mya only had 3 top ten hits

Aaliyah had hit after hit "One in a Million" (#1 R&B Airplay), "Try Again (#1 Hot 100), "Back and Forth" (#1 R&B), "At Your Best (You Are Love)" (#2 R&B / #6 Hot 100), "If Your Girl Only Knew" (#1 R&B), "The One I Gave My Heart To" (Top Ten Pop / Top 10 R&B), "Are You That Somebody?" (#1 R&B), "I Don't Wanna" (#4 R&B).

Can't compare.
