those idiots took advantage of her voice trouble in the Up! world tour :( , she has been doing live performances since she was 8 years old and she has always been an awesome singer! her voice is amazing and it's not computerized or nasally, but it only changed a bit because of the exhausting tour ( she mentioned that in 2005, she's a great honest person), and at the present time her voice is back, the proof is "you needed me",so don't you ever listen to anyone would say that about Shania!,she'll rock our world with a great hit CD without any of Mutt's help :)
She was honest and knew her voice had been weakened towards the end of the Up tour and those GHs songs, although it sounds better with "You Needed Me" and at the 2006 Kennedy Honors. I will say though, I noticed her voice from the early 90s into the late 90s was much different then the tone of her voice when she came back in 2002. That comes with hormonal changes with having a baby as well as getting older, it happens to us all. Some prefer her singing tone of her earlier career, some of her more recent years...
