I've watched all of her tours and I don't think her voice is worsening.
I love her deep voice now... it's very beautiful.
Where's the evidence of her "worsening" voice that everyone is complaining about? I'm not sure I can understand what's so bad about it unless I'm not listening to the right stuff...
Even if her voice IS worsening and some people do not like her newer style, I still love her! (and yes I am one of the few who loved Guilty and NEXT LEVEL).
A link, please?
