Query: One Heart

This certainly was a major disappointment. I have always loved every song she has ever sung. What happened? I am not alone. Everyone I have discussed this with agrees. Something terrible has happened with her music. She has such a great voice when singing her ballads. She is right up there with Babs. She's sinking fast with the new producer. Bring back David Foster! These other guys are good, but not for her. Her special voice and talents are being neglected. There's nothing better than David Foster producing her songs as he knows how to bring out the best in her.
