It seriously depends on what kind of music you like and what kind of sacrifices you're willing to make when trying to rate a female singer, style, talent, lyrics. The names you listed are good ones to avoid, but then you have some girls who are very talented and real, but a record company has decided to over market them automatically making them suck. Take Jewel for eample, yuo listen to her old stuff, and she comes across as talented, if not a bit wishy washy, and now look at her... Record company wants to market a new image for her, she's wearing stupid clothes and singing soul-less music with no inspiration. The Music buisniess is a fickle machine and when it comes to females in the business it's really hard to decide because they don't get the respect they deserve, well at least some of them, and then the label decides they need to change their act, then, disaster...
