I agree with FancySN, it's all a matter of taste... Just because some people don't like Ashlee's voice, doesn't mean its bad... Most people I know hate Ayu's voice, yet I think its great...
I mean, leave these kids alone. . . They are rich, (or their family is) they can make a record if they want... I mean back in the 70's all the pop idol singers couldn't sing... NOTHING has changed, get over it. And i'd rather listen to wannabe punk teenage girls than ANY rap song... I'd also rather listen to a HUMAN being sing, not weirdo robot-women who show-off with their overdone vocals (Mariah, Whitney, Utada)... And leave Hilary alone, Disney sewed her vagina shut.
