Query: Her voice is lovely , but the caliber of music is premature.

Charlotte has a great deal of potential. With time and tutoring she will blossom. Her debut CD simply should not have been so difficult. She struggles often and sings out of her strongest range. At many times during the CD I really enjoy listening. However, there are also times when I cringe. I find it difficult to listen to the entire CD without gettting annoyed by her immaturity. The problem is that she is marketed as a prodigy and expectations are set incredibly high. (ie. She's no Michael Jackson or LeAnn Rimes) I do look forward to her future career and listening to her as her voice matures in the years to come.
