Christina Aguilera?

She's been around since about '99 and I've listened and enjoyed several tracks. But, now I draw the question, who is she? What is her genre? What does she excel in? Who is her audience? Pop/Soul? Pop/Rock? With her new disk, Bionic, hitting stores today (June 8th), I listen and I enjoy some tracks, most, but not all and this is totally different than anything I've ever heard before. She's auto-tuned in so many, the powerhouse vocalist is unrecognizable. I have no idea how I feel about Christina Aguilera the artist and what her legacy will be. I'm all for reinvention, but with this being her 4th studio album, how many times can she truly reinvent herself, her sound, and her image? After hearing her rendition of This Is A Man's World at the 2007 Grammy's, I can never deny her talent. But, I still question, who is Christina Aguilera?
