^ your a dumbass for listing those people..

rihanna, ciara and cassie (to a certain extent) CAN sing... just because you cant shatter somebodys ear drum dont mean you can't sing.

YOU do homework and actually look for videos of rihanna live... recently... at glow in the dark... girl can sing...

ciara dont need to sing... she is an entertainer

cassie... vocally improved studio wise.
