heh i dunno why :D :D but no one mentioned these people who have bad ass voices (despite their public personality)
Christina aguilera (2nd album, first one was garbage)
Mariah Carey
also...
lauren hill
pink
mya
aalyiah
alisha keys
the last chick to get in destinys child
kelly clarkson ( dood you gotta admit... shes got a strong set of pipes (although I only like her because she sings alot like christina aguilera)
I determine these picks by the ability to watch their musi videos with no picture, for pretty much all the the ladies on my list when I see their videos to their songs I have a sudden urge to turn the picture off and just leave the sound on ... videos dont do justice tho their voice
where as on the other hand you have other "vocalist" who's videos you feel like muting and just watching the picture = Britney Spears, jessica simpson,the lead singer in destiny's child ... ect...
