Beyonce was already known from DC. And like zzmyth said, Beyonce has had more time in the industry to let her albums marinate and gain more sales. Oh well...
Meh not really news imo......just because of all the * that would be involved for most. Plus I don't think its completely fair to ignore Destiny's Child......
If both stopped producing music today Beyonce's footprint on the industry would be considered far more significant.
