She was bigger post death, but still rather mediocre...
At the time of her death I had never even heard of her. Yes I was only ''11'' but as a tween I was up on all the popular singers of the day and Aaliyah was not one of them. Don't write this off as some type of entertainment industry racism either. The singer ''Brandy'' for example was a HUGE star and as popular as Britney Spears and Christina Aguilera (sic) back then. And there was already huge hype about Beyonce while she was in Destiny's child. ''Survivor'' spent weeks at number 1.
Aaliyah for whatever reason was just not picking of steam while she was alive. Her music barely got any airplay. Her vocals were rather bland in comparison to other R&B singers her gender and age at the time many of which had extremely strong vocal ability (Beyonce, Monica) while Aaliyah did not. But then post death her album started to chart and the radio stations were playing her songs and MTV was playing her videos even far into the next year.
To be honest she was rather mediocre all considering. Most of the fame was gained post death. It is very unfortunate what happened to her regardless..
